I still don’t feel easy about where that came from.
Nor do I, Lathyrus. It's a non-sequitur for a start, is dangerously close to Godwin's Law, and is using centuries of anti-semitism and actual discrimination very distastefully to try to score points in an argument.
Firstly, there is no correlation between anti-semitism and concern about women's rights being eroded, and our very existence as a sex-class being called into question. None at all.
Secondly, however dubious, an attempt to link such concerns to anti-semitism is, insofar as the analogy holds, suggesting that those who hold them are transphobic, and by extension have murderous intent towards transpeople, which is not only ridiculous but offensive.
Thirdly, questioning the biologically impossible assertion that TWAW is not transphobia in any case.
