Am I correct in thinking that Sisters Uncut were involved in the assault by Tara Wolf on a 60 year old feminist in London 2 years ago
Yes. They are TRAs through and through.
I came here to add my tuppence about the donations fiasco - people donating to certain groups without realising they are actually TRAs, then wanting their money back. TRAs are going apeshit on Twitter about that.
An analogy - you want to help people in a warzone, so you donate in good faith to a charity that is giving them food and shelter. Only after you've donated do you find out that the 'charity' is also buying arms for one of the sides in the conflict, and actually causing more pain to civilians than it's relieving. You obviously want your money back. Well... that's the kind of situation we are in.
