"Most recently, Germaine Greer made headlines (in queer media circles) for appealing to a bad vagina smell as being essential to authentic womanhood. During a question and answer session at The Cambridge Union, in which she again asserted trans medical care to be unethical, Greer suggested that trans women aren’t truly women because trans women don’t know what it is “to have a big, hairy, smelly vagina.”That's fairly typical. First a bizarre test of what sex someone *really* is - this one, genital aroma, is in fact an article of faith amongst TERFs (Trans Exclusionary Radical Feminists), Then the unevidenced assertions that Trans women don't pass the test due to diametrically opposite reasons - one because they do, one because they don't - all asserted without a shred of evidence.
Interestingly, prior to Greer asserting that trans women don’t have smelly vaginas, Sheila Jeffreys asserted that trans women have incredibly smelly vaginas, asserting, “The newly carved-out orifices of male-bodied transgenders do not resemble vaginas [and] create new microbial habitats in which infections develop and cause serious smell issues for their owners.
The Religious Right is anti-Trans because Transsexuality undermines a well-ordered society where men are men and women are women, that it's all a Leftist plot to undermine the Gender Binary. (See former pope Benedict's speeches on the subject).
The TERFs are anti-Trans because Transsexuality upholds the Gender Binary, and that Trans people are tools of the Patriarchy.
This appropriation of Trans people is discussed well and with some wit at http://quinnae.com/2010/10/01/i-am-whoever-you-say-i-am/
As an aside, the microbial flora in neo-vaginas is nearly identical to that of the usual kind in premenstrual girls, but that's merely a fact and so irrelevant to the issue.
"Weyers and his colleagues studied 50 postsurgical transsexual women and found microbial microflora that were simiilar to those of premenstrual girls:
Our study indicates that the microflora of the neovagina is characterized by bacterial species from the skin and the intestinal microflora, somewhat similar to what is observed with premenarchal girls…They also found microbial populations similar to those of women with vaginitis, and they noted an absense of lactobacilii (which is present in the vaginas of ovulating women, but not in girls) in all but one of their subjects."
But to go into this just buys into their irrationality. Like trying to argue with Flat Earthers.
