As a gay man I hate a lot of the (supposedly) positive stereotyping that goes on too.
I mean, you get the traditional homophobes who think that all gay people are depraved predators who are coming for your kids, but there is also another set of people who have unreasonable standards that you should be their own personal 'Queer Eye' or whatever. You should be an expert in art, fashion and design, an expert cook and have perfect hair/skin/teeth/abs and whatever else.
More than once, someone has accused me of not being a 'proper' gay because I don't meet some standard of gay perfection they have in their head. It is not as immediately dangerous as, for example, being black where some policeman might just shoot you for fun (though it still isn't safe to be 'obviously' gay in a lot of places --even in Europe). However, it puts pressure on a group that struggle far too often with not feeling good enough that they are meant to meet some unattainable standard of perfection.
