Well, they are the ones who raised Sylvia Rivera and Marsha P. Johnson to the level of Queer Sainthood and have tried to insist that Marsha was a trans woman. But then, I seem to recall reading some interview with Rivera later in life when she said that she was "tired" of the term 'transgender' or something like that. I actually don't think Rivera ever entirely bought into the whole "trans women ARE women" dogma.

What is pretty clear from the older books on gay history is that contemporary gender ideology did not exist 30 years ago. The current dogma is a very recent invention.
