Number one, the gay rights movement as we know it started with Stonewall, which was a bunch of drunk and trans queer people rioting after a bar was raided. The gay pride parades we know today (raucous, noisy, in your face, taking over the streets) started in 1970, and definitely included people who were expressing alternate forms of sexuality, including kink. There were marches before that, with people dressed in gender-conforming clothing, respectfully asking for their rights (or at least not to be arrested for having sex with someone of the same gender).
There has always been a tension in the gay/bi/lesbian/trans/queer/etc community between those who think the best route is to prove that we're all just like everyone else, only more respectable, and those who are pushing the edges of conformity. That goes right back to the start of the gay movement as we are familiar with it from popular culture.
And, boy oh BOY, are the people on both sides judgmental about the choices other people make. The ones aiming for conformity believe the others are disgusting or wrong, and too "out there." The ones aiming to push the fringes believe the ones aiming for conformity are in denial of the real issues. And they both believe the other side is distracting from the ultimate goals of the movement. Mostly because it's not just one movement.
Oh, and then there are the people who are just in it for the party, and I don't see anything wrong with that.
My guess is that the world needs all kinds of people, and that it's really hypocritical to judge how other people live and act in the world... well, okay, I'm VERY judgmental, but then, I'M
