I really should stop reading these threads on here. Having been in an abusive marriage, and been assaulted twice by my ex wife, I should have learned by now that there will always be people on Mumsnet who hide behind "nobody should hit anyone", and then go on to explain how it doesn't really matter when men are victims because of wider trends.
Women are affected more. Men have power. Men can do more damage. Women must have been provoked. Men are naturally more violent. Men are stronger. It's a problem when men are attacked because it distracts from the real problem of women being attacked. Some of those things are true (women experience abuse more than men. Often the offences result in more serious injury. Yes, all true). Some are clearly not (the provocation argument is utter bullshit). But when those reasons are used to qualify NSHA to explain why my experience, and that of the OP's son, really isn't that important, because we should really be talking about female victims, it is not okay.
It's nonsense, as any man who has experienced this can tell you. It doesn't matter that I'm physically stronger. I could never have brought myself to hit her, or do anything else to hurt her. She knew it. She used it. She had the power, and she wasn't afraid to use it to keep me in my place. But Mumsnet thinks I had the power. Because, penis. Well, bollocks to that.
I'm sick of the whatabouttery from people like @bertrandrussell who decide that a man being assaulted is little more than an opportunity to talk about men assaulting women.
We're people, too. We deserve to be supported without people deciding that we should actually be talking about women.
Women abuse. A lot. Not as much as men, I recognise. But that isn't a reason to silence male victims, or tell us that we should really be talking about male abusers. When you play in all that wider societal stuff (and I recognise that it's all valid) to silence the experience of male victims, you're participating in the abuse.
