Well do YOU think that men can be pregnant?
If you don't you are a Terf too. Trans men do get pregnant and a whole raft of language has changed as a result , cf pregnant person, chest feeding.
It's trans exclusionary to think that only women can be pregnant.
Years ago King tweeted something similar and was bashed online for it, I can't remember the exact tweet but it followed with an attack on JKR and a tweet along the lines of Trans Women are Women.
It's not unreasonable to point out that this is an inconsistency.
Isnt it interesting that Trans women are women but trans men are ALSO women?
