All this group culpability shit does is palms the problem off onto some vague group, most of whom won't do anything as they're not violent themselves and don't associate with violent men. It hasn't worked in the past and it isn't working now
Tbh if I was a man I'd think very carefully before stepping in to help a stranger. Especially if the people telling me it was my duty were actually 4x less likely than me to be assaulted by a stranger. It doesn't matter that men are bigger and stronger than women because most non violent men aren't good at fighting and plenty of thugs carry knives nowadays, which they're more likely to use on someone they're unlikely to beat in a fistfight.
Look at the middle aged family guy from Land Rover who challenged a load of 14yo boys for their behaviour and was fatally stabbed. Bet his family wish he'd not stepped in.
And you can be sure as a man that nobody will step in and help you if you end up being the victim. Just look at all the social experiments on YouTube. They usually feature a staged encounter like where one partner chokes the other up against a wall. When the woman is the victim people rush to help. When the man is the victim people laugh and film it on their phones.
I've heard people on here try to argue that people are usually less concerned for the man because a woman presents less threat to him than the reverse, but how does this explain people finding it hilarious?
The thought of stepping in to help a stranger and ending up getting your head stamped on whilst people laugh and film it doesn't really sound appealing tbh. And in many cases the abused woman will still side with her partner. I remember somebody on here recounting a story where the abusive husband claimed the good samaritan had started the fight and the woman actually corroborated this and went against the guy who'd tried to help her.
