> There are a lot of trans people who have no interest in conforming to gendered expectations, but are coerced to by the threat of losing access to medically necessary healthcare. ... GCs in places like the UK ... want to reinforce silly stereotypes like "if you don't wear a dress you're not a real trans woman".

Well, historically, the broad shift from a focus on "transsexual" status and "sex change/reassignment" (focusing on primary and secondary sex characteristics) to one on "transgender" and "gender reassignment" (focusing on some canonical gender expression) was driven by consensus within the trans community.

If anything, the more traditional or "gender critical" POV is that the earlier 'transsexual' focus was in fact appropriate, in which a transfemale person can be transfemale no matter what they express as, whilst "cis", "trans" or "fluid" gender expression is a bit of a red herring.
