But the whole sex celebration element of things like Pride is not that new, there has always been a group within the gay community, mainly men, who have equated homosexuality with a special identity and a rather libertine approach to sex.
I have thought in recent years that while these elements seemed to co-exist in the past, they have always been at odds on an ideological level. And the latter group now seems to dominate a lot of LGB groups, perhaps in part because those in the other group didn't so much want to spend their time in sexuality focused groups.
Certainly in the UK long before T was even a thing, many lesbians opted out of so called Pride celebrations because it was very male, but also was very fetishistic. I dont even think it was a celebration of sex. Its more that people who are a fringe element thinking they can hijack a wider movement because that movement has recently been accepted and celebrated.
A complete contrast to having a gay rights march were the very opposite was the purpose. ie to have people in their every day clothes, eg that they went to work in, including those in uniforms, to show that being lesbian or gay wasn't in fact that extraordinary, because the people a who are that are just ordinary members of society.
So I think the queer agenda was there some years prior to the T being included, because those pushing the queer agenda didn't in fact prioritise what was the primary purpose, a celebration or affirmation of people who are same sex attracted. For them it was just a vehicle to push their politics. Thats why the T agenda was so useful.
... challenging the notion of defined and finite identity categories, as well as the norms that create a binary of good versus bad sexualities. Queer theorists contention is that there is no set normal, only changing norms that people may or may not fit into, making queer theorists’ main challenge to disrupt binaries in hopes that this will destroy difference as well as inequality. ...
The irony being of course that the T agenda is in fact totally about being different (special) and revels in preceived inequality as part of setting themselves apart and above from everyone else.
