I spent a lot of time on the streets in New York City in the 1990s with Queer Nation and Act Up. Anyone who thinks those movements were not militant or didn't need to be militant was either not around at that time or hasn't done their reading.
And that brings up another point – while Queer Nation and Act Up might be thought of today as having been primarily LGB, they were not. The T was very present in both movements, and I know that because a bunch of the Ts were my personal friends. Transgender people have always been an inseparable part of our movements toward equality and acceptance, for the common-cause reason you wrote so well about.
