I agree with lang about 11 posts back.
The reason why I suppose it's helpful for women (repeating myself) is simply that the TRAs have been so very set on labelling any of the concerns set out by WPUK, which over lap with the concerns on angry bird's thread and in this letter. This letter included some of the points that WPUK make.
Of course it's transsexuals speaking up for themselves but as I said before in this very apparently polarised debate on twitter, it shows that the Rad Fems and the TSW are able to act as allies. It calls for reasoned debate.
I for one actually feel less scared to speak about my newly acquired rad fem ideals in relation to anything linked to trans simply because I know many trans people have this view and aren't into the batshit crazy crap of the woke unicorn umbrella spectrum lot. And are querying self ID from their own perspective.
They didn't have to speak up, so loudly, in a publication that has been trashing women bar a few of its contributors attempting to occasionally try to redress the balance. So I do say thank you.
