If a man was caught on video throttling a white woman there would not be a single post on Mumsnet defending him and saying that she asked for it. I'm 10000% certain of it.
Mumsnet is the most racist forum I've ever seen in my entire life.
The threads about George Floyd were a disgrace, people acting like he deserved to be murdered in cold blood.
The threads about Ahmaud Arbery were full of comments implying he might have been guilty (of nothing, since he was not accused of anything) and defending the redneck violent thugs who just wanted to chase down and lynch the first black man they saw.
There was a thread recently over a black woman who was harassed and assaulted by police over an issue with her being suspected of not having swiped in properly on the bus (she had paid), lots of racism, lots of comments indicating that being assaulted is just what you should expect if you don't bend over backwards for police, and some posters sharing personal experience of getting away with not paying (as white people) or seeing white people not challenged for not paying, and then other posters attacking them.
The threads about the BLM protests in 2020 were full of outraged screaming about thugs, from the same posters who were out in droves playing the "I don't agree with them but I support their right to free speech" card in the threads about the white supremacist/Neo Nazi rallies.
but they have chosen a poor figurehead.
No one has chosen her as a "figurehead" ffs. Pointing out that throttling women is not an appropriate response to shoplifting is not making someone a figurehead. Besides the woman in the bus incident had done nothing wrong, yet there was still pages and pages of demonising her.
If this was a white woman the discussion would be completely different. You know it would be.
