Also known as The Egyptian Diamond

Quoted in part in Randall Garrett's SF short story "The Foreign Hand Tie" 1961 writing under the pseudonym David Gordon and until recently, erroneously attributed to him.

It was originally published  in the children's magazine "St. Nicholas" No 19 part 2 in May 1892.

The Confederate Manifesto

Source : Cornerstone Speech, 1861, Confederate Vice President Alexander H. Stephens

“The prevailing ideas entertained by most of the leading statesmen at the time of the formation of the old constitution, were that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally, and politically. It was an evil they knew not well how to deal with, but the general opinion of the men of that day was that, somehow or other in the order of Providence, the institution would be evanescent and pass away.

A fair and accurate assessment. It is true of Racism today - an evil we know not well how to deal with, but which we trust will pass away.

The events of the 40s show that such passing may have to be assisted by means up to and including the use of nuclear weapons on organised Racists. Or conventional weapons in suitably horrific quantities. Hamburg. Dresden. Rostock. Tokyo.


Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the government built upon it fell when the "storm came and the wind blew."
Our new government is founded upon exactly the opposite idea; its foundations are laid, its corner- stone rests upon the great truth, that the negro is not equal to the white man; that slavery — subordination to the superior race — is his natural and normal condition.

This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth.



The first, but alas, not the last. Hence Auschwitz. Hence Hamburg, Dresden, Rostock, Tokyo and other cities not completely razed by Firestorm, just gutted.

Many who hear me, perhaps, can recollect well, that this truth was not generally admitted, even within their day. Those at the North, who still cling to these errors, with a zeal above knowledge, we justly denominate fanatics. All fanaticism springs from an aberration of the mind — from a defect in reasoning. It is a species of insanity. One of the most striking characteristics of insanity, in many instances, is forming correct conclusions from fancied or erroneous premises; so with the anti-slavery fanatics; their conclusions are right if their premises were. They assume that the negro is equal, and hence conclude that he is entitled to equal privileges and rights with the white man. If their premises were correct, their conclusions would be logical and just — but their premise being wrong, their whole argument fails. “

Bottom line: the Might Makes Right Racists lost. Twice. Once at Appomatox Courthouse, once at Luneburg Heath. Don't punch Nazis, eradicate them. Hopefully by education rather than incendiaries.

"Gender Reassignment and case of "John /Joan" - Dr. Milton Diamond with...

I had some very interesting discussions with Prof Diamond when I visited him in Hawaii some 15 years ago.

To my knowledge, none of those pictured are Intersex. Certainly none are Trans. Humans vary.

A short history of Sex Chromosomes

In 1890, the X and Y chromosomes were discovered. It was found that the men who were tested had 46 chromosomes, including an X and a Y, while women who were tested also had 46 chromosomes, including 2 X chromosomes. 

So obviously the conclusion was that the Y chromosome defined masculinity. A reasonable conclusion. 

 Fast forward 50 years... and it was found that some men had 47 chromosomes, including 2 X's and a Y, while some women had 45, including only one X. Still no problem with the "Y chromosome defines masculinity" idea.

 Then... it was found that fully 1 in 300 men weren't 46,XY. Some women were. 

 Oops. 

 After DNA was discovered in the 50s, it was found that the SrY gene, usually found on the Y chromosome, sometimes was missing. And sometimes had been translocated to another chromosome, hence 46,XX men and 46,XY women. So SrY defined masculinity. Whew!

Then.. it was found out that some men didn’t have an SrY chromosome, not anywhere. Some women did. Other genes were involved sometimes.

Oops again.

. Worse, other factors, such as Androgen Insensitivity made 46,XY people female, and Congenital Adrenal Hyperplasia masculinised 46,XX people. 

Then in the 70s, other syndromes, such as 5alpha-reductase-2 deficiency were identified, which caused babies to look like one sex at birth, then the other at ppuberty.Even worse, in some places 1 in 50 infants had this natural sex change, it was not rare there. 

 Science 1974 Dec 27; 186 (4170): 1213-5

 In an isolated village of the southwestern Dominican Republic, 2% of the live births were in the 1970's, guevedoces....These children appeared to be girls at birth, but at puberty these 'girls' sprout muscles, testes, and a penis. For the rest of their lives they are men in nearly all respects.

 In the 90s, it was found that hormonal hiccups in the womb caused some parts of the body to develop as one sex, othersbas the other, regardless of genetics.

Male–to–female transsexuals have female neuron numbers in a limbic nucleus. Kruiver et al J Clin Endocrinol Metab (2000) 85:2034–2041 

 The present findings of somatostatin neuronal sex differences in the BSTc and its sex reversal in the transsexual brain clearly support the paradigm that in transsexuals sexual differentiation of the brain and genitals may go into opposite directions

 It's a matter of timing during foetal development.

 Sometimes a boy is born looking like a girl, sometimes a girl is born looking like a boy, regardless of chromosomes. 

This is complex stuff. We don't teach the Theory of General Relativity in grade school, Newtonian physics, or at most Special Relativity (far simpler than General) is enough. Similary, "XX is female, XY is male" is good enough unless you do medicine or biology in college.

 It's only really relevant when talking about Trans or Intersex people, just as Relativistic effects only become relevant in the domain of the very big, very small, or very very fast, close to 186,000 miles a second.

 People do *not* need psychiatric help when they think that things get heavier, more massive, as they go faster... while lengths contract. People do *not* need help when they think their sex is something different from their genetics.

 Intersex people exist. Trans people exist. They are unusual, so trying to apply the usual approximations is as silly as trying to apply Newtonian physics to things moving close to or at light speed. Legislating such things is as insane as legally ruling that Pi=3... as has been done in the past.

Masks - from the Journal of Hospital Infection

 From

Dismantling myths on the airborne transmission of severe acute respiratory syndrome coronavirus (SARS-CoV-2)

Tang et al, Journal of Hospital Infection, Jan 2021 pre print

Several laboratory studies have already shown that surgical and home-made masks are somewhat (but incompletely) effective in both limiting exhaled particles, and in protecting wearers from inhaling particles from others. Surgical masks can contain, and therefore reduce, the dissemination of viruses shed by an infected wearer by up to 3-4-fold (i.e. ∼67-75%), and even 100% in the case of seasonal coronaviruses., When an infectious person wears a mask or face covering, the size of the exhaled plume is also reduced and this also helps to reduce the risk of exposure to those nearby.
 
Surgical masks also protect the wearer, by reducing the exposure to incoming droplets and aerosols from infected individuals by an average of 6-fold (range 1.1 to 55-fold)., The filtration capacity of surgical masks in the micron size range is often considerable, although it varies between brands. We know that the filtration capacity of N95/FFP2 respirators is better if they have been appropriately fit-tested, to avoid leakage of aerosols around the side of the respirator into the breathing zone.
 
Even home-made cloth masks (made from tea cloths or cotton t-shirts) can reduce the exposure from incoming particles by up to 2-4-fold (i.e. ∼50-75%).
 
This mainly depends on how the mask is made, what materials it is made from, the number of layers, and the characteristics of respiratory secretions to which it is exposed. Based on the evidence supporting a role for airborne transmission of COVID-19, the use of N95/FFP2/FFP3 respirators by frontline healthcare workers should be recommended. For those that cannot tolerate wearing these masks for long periods, the less restrictive surgical masks still offer some protection, but it needs to be acknowledged that these won’t be quite so effective

Meet Elizabeth from Knoxville Tennessee who stormed the Capitol.



Treason doth never prosper, what's the reason? For if it prosper, none dare call it Treason.

Corollary: it's only a Revolution if you win. Otherwise it's Treason. Really. Not joking.

Worse, in the US, if someone was killed during the course of a crime, everyone involved in the commission of that crime is guilty of homicide. Even lookouts or getaway drivers who had no direct connection with the death. As icing on the cake, if the person who died was a law enforcement officer, all those involved are deemed "cop killers" and hunted without mercy. One Capitol policeman died from head injuries after one of the mob bashed him with a fire extinguisher.

This naive idiot is about to find out that in real life, actions have consequences. Legal ones.

 The crime of Treason in the US is very, very rarely charged. The bar is set very high. However, the Death Penalty is on the table if found guilty. I hope this child in a woman's body gets good legal representation, and that the prosecutor is not out for blood. Literally. If she's really unlucky, she'll  be tried as if she were Black.
