When I was last involved with this thread (or, probably, one of its ancestors), many of the “transwomen/men are not women/men” side were still tying gender directly to sex, that transition were arbitrary, and using many of the myths debunked in that video. Eventually, I gave the thread up as a lost cause when I was accused of playing dishonest semantic games when I tried to explain that gender is a social construct, related to gender but not necessarily tied to it.
If that has changed and the thread is to the point of recognizing that transwomen possibly have some female physical traits and might in fact be women, and transmen the reverse, then I absolutely congratulate the thread for making more progress than I would have thought possible.
The Gen X cynicism in me suspects that is not actually the case.
