I follow someone on twitter who said her friends daughter was stabbed in the leg on the bus by a boy she'd refused a date with. Despite evidence, CCTV, nothing was done, he had a slap on the wrist and she was advised not to take the bus.
"Do you really want to do this?" "He has such a promising future" "boys will be boys" "I'm sure he's very sorry" "you'll ruin his life" "he's only joking" "yes I can see that's not a nice message to receive but he hasn't actually hurt you has he?"
It's all very well educating our sons but what message do they get when VAWG gets a bloody slap on the wrist?
Porn/Incel movement/Misogynistic influencers have a lot to answer for. Men who've grown up with a message they're entitled to sex, entitled to affection, entitled to women's bodies. Like we're pieces of meat. Choking, hitting, spitting, and girls thinking that's what sex is 
But the lack of action is also to blame. Nothing gets done until a woman or girl is killed. And then it's too late. You can't bring her back.
None of this maaaaate bollocks. Throw the fucking book at each and every one of them. Shut down this normalisation of violent porn. Ideally get it all offline. It can go back on the top shelf of the newsagents with a strict age limit and no violent content whatsoever. Cut every one of those misogynistic dickwads off at the socials. Same for any online incel message boards, egging each other on in an echo chamber of woman hate.
But then that's too much fucking effort isn't it.
As a mother of a daughter I'm absolutely horrified and saddened, both by today's events but knowing unless there are some serious fucking shake ups, that poor girl won't be the last.
