Well, that’s your opinion. Transwomen are not “Edge cases.” They are men. Jonathan/Jessica Yaniv is a man. Rachel MacKinnon/Veronica Ivy is a man. This person is a man, and in over a thousand posts no one has come up with a coherent reason to think otherwise except “words change,” which doesn’t change the underlying concept, which should travel with the word.
Someone who has actually had sex reassignment surgery, well, you would have a point there - but in fact that is NOT what we’re talking about, nor are we talking about people with intersex conditions. We’re talking about people with penises who claim to identify as women. Men.
