I certainly don't think the much more widespread acceptance of gay people is a bad thing, but i certainly find the incredible conservatism of mainstream gay culture rather disturbing and regrettable. The main aim seem to be to get recognition and rights to marry, which is hardly a radical step, if anything its deeply backwards. What happened to being queer and the attitudes that came with it. Its not just about gay or bi people, or even trans, but everyone should be questioning and challenging the institution of marriage and the rigid attitudes to sexuality and gender.
I still describe myself as queer (at 25 so i missed it all!). You can be 95% straight and still be queer, that the point. Its a recognition and celebration of the wonderfully messy, transitory, fluid and fabulous human condition where we should be able to fuck who we want, how we want. Where sexuality isn't fixed or binary, gender is an identity not a prison or a set of expectations of personality and working life, sex is varied, fun and with as many or as few people as you like.
Nobody gay or straight, or wonderfully imbetween, should be forced into the restrictions of a single legitimate relationship structure of one man and one woman, or even two men (where the assumption is always that one is 'kinda' like a woman anyway).
