@Belichtofalicht: "Posters here deny completely that men can be women in any way at all….ergo, trans women do not exist".
Nope. Not at all. That's a super example of a non-sequitor. What does follow ("ergo") is only that trans women (like everyone else) cannot be men who are women - a somewhat unexceptional truth.
I find this misunderstanding about existential consequences of mere description hard to fathom. Yet it seems quite common in such discourse. So it might be worth looking at again.
Try to understand, @Belichtofalicht. To claim your description of yourself is false is not to claim you don't exist.
--Try with other descriptions:
"I'm cool, me!" ... "Erh, no you're not." ... "Aargh, you're claiming I don't exist!" ...
"I'm Elvis, me! I swear I am! I'm Elvis!" ... "Erh, no you're not, you're just that guy works down the chipshop." ... "Aargh, you're claiming I don't exist!" ...
Compare:
"I'm a woman, me!" ... "Erh, no, you're a man." ..."Aargh, you're claiming I don't exist!" ...
... "Do stop being so silly."
Understand, @Belichtofalicht (and others)? Think about it.
