Some of them used to be mens rights activists who think women have it better in life because of equality legislation etc. They then become trams women but their hatred of natal women still remains. The trans community needs to stand up to male violence instead of concentrating all their ire on 'terfs' who are just women who want to have spaces away from men and away from persons with penises. Trans activists when they say trans people are at risk of being murdered dont say by whom. They blame male violence on women. They dont distance themselves from the violent aggressive language of other trans activists and when trans do people speak out against violent and aggressive language they are shut down by trans activists.and the ones who say that, personally make it harder to see them as women. They don't understand the aggressive manly language they're using, these are the kinds of things that have been shouted at women on the street, the kind of thing aggressive men send you when you reject them online. The ones that react like that make you think they're part of the group that does it because it's trendy, you can't say you're actually a woman then act like a man does. I think that's what JKR was evoking if I'm not mistaken.
