Trans women have to be male in the first place. It’s a prerequisite.
More suppositions, still no evidence. What a funny flavor "objective" truths come in these days!
Oooh, I'm a transwoman! I said so, so I get to be. The objective and observable fact that I have a female body, with a female reproductive system (what's left of it anyway), and a completely normal female karyotype shouldn't be a barrier to me identifying as a transwoman.
Anyone can be a transwoman if they want to be. Or a cisman.
Wait, I've changed my mind. I'm a cisman. It totally say so and words mean whatever the fuck I want them to mean in whatever way makes me right. So there. Logic!
