You see the more extreme placards etc at any protest.
My understanding is that it is not women in general the trans community feel aggrieved by, it is the section of women that won't accept their community. I'm not saying which side of this argument is correct, I can see both sides.
I do think the argument that the trans community hate all women is just a lazy interpretation. Feminists don't hate men, but will vocally attack men who promote inequality for women.
I do feel as though Mumsnet has become a very different place in recent years. It used to be somewhere that people would do isten to a range of viewpoints, agree disagree whatever... But not this hysterical mob mentality.
