I'm glad some transsexuals are finding their own voice to oppose self-ID and other aspects of the TRA agenda.
It would be a mistake to lump that voice in with women's voice although I understand the temptation to do so. For women it can be seen as lending extra legitimacy to our campaigns if some TS 'agree' with us. For TS, it's a numbers game I imagine - there are very very few gender critical TS because TS are a tiny population to start with, so joining forces with women can provide safety, support and amplification of their message.
TS people have their own agenda in this debate though and we should expect huge, dare I say 'fundamental', areas of disagreement. Uncritically lumping ourselves all together as 'allies' risks papering over some cracks the size of canyons.
Forming political alliances OTOH, respectfully and with full, honest acknowledgment of our differences, can work well.
