The actual ordnance doesn't quite do that. According to the Good Folks who made this advert:
On January 28th, 2008 the Gainesville City Commission passed a (PDF)Gender Identity Ordinance granting special legal status to people who suffer from gender identity disorder.The same special status that blacks, jews, christians and other humans have. The same protection that others have against discrimination based on "sexual orientation, race, color, gender, age, religion, national origin, marital status or disability". It would add "gender identity" to that. That's all. You can read that for yourself, on their own website. They're betting that people will just look at the pretty pictures instead.
It's not just the bigotry: it's the hypocracy. Hence the award of BSS 6 to this video. Why not 7? They didn't make the guy black, or wearing a yamulka. It could always be worse, trust me.
