That's threats, though, vestal. I think threats are different than someone just calmly and politely holding a different viewpoint.
Sure, it is threats, but it is the way genderists argue - either explicitly, or implicitly, by using words like "terf", that anyone who has been on the receiving end of it knows implies a threat.
Of course, I would not feel threatened by them simply stating their ideas about biological sex not being real; if it was just a theory. I once attended a whole hour's talk about Judith Butler. (Who I am not sure is a genderist, but apparently did propose that sex allegedly is socially constructed. Hard to say because she's famous for her overly complicated writing style.)
I thought it was nonsense, but why would one feel threatened by someone else talking utter nonsense?
I can calmly listen to people arguing that the earth is flat, no problem.
But with genderists, there's always the underlying threat. They openly admit to being allies of those who want to murder me.
I don't feel safe being in a room with them. (But of course think they should be allowed to voice their opinions. I have to know who they are so I can get the hell away from them)
