That’s a nice tautology you’ve got there. Regardless, looking at people who explicitly say “we are not women” and then saying “they’re women” seems a bit rude and dismissive of their life experience if you ask me. Personally, if a person with a full beard, an imposing physique, and a deep voice says “I’m a man”, I take them at their word. I guess you might ask them to drop their pants to see if they’re really a “woman”, though.
The only reason it can be a tautology is because of the fact that women are the only ones who can get pregnant, it’s an observation that accords with reality.
I’m willing to go along with a lot of things an individual wants, calling them a name of their choosing, not bringing up the obvious incongruities in their appearance etc all out of respect, so much of it is simply breaking gender norms that why wouldn’t I? But I’m not the one breaking the spell here, they are, men can’t get pregnant, that’s not breaking a gender norm, that is an impossibility and I’m not willing to go along with such clear nonsense. If they want to continue the charade then don’t get pregnant. That’s not on me or anyone else.
