I think mumsnet is holding a unique position in this debate, at the moment.
It's full of educated women who know exactly what they're talking about. It's not allowed to degenerate into a mud slinging exercise. Personal attacks get deleted.
As far as I know, it's the only site where discourse can happen, based on an actual dialogue with fully informed people, without recourse to a never-ending exchange of memes, emoticons and insults.
It's also rather telling that the only transwomen who stick around, are the ones without a massive axe to grind. Transactivists always flounce.
Holding this ideology up to civilised scrutiny, only ever goes one way. Complete collapse.
