Some guys do indeed lash out at women a lot. It's a problem that a lot of effort has been put into tackling, but with limited progress. There's two things there, gender attitudes and violence attitudes. Some people have seriously negative attitudes toward the gender they don't belong to. Sexist attitudes and gender-hatred are major problems society needs to tackle. A lot of common attitudes need to be rethought. And some people seem to think it's ok to carelessly lash out at other human beings with violence. It's all too common. Human nature is violent. Male on female violence, male on male violence, female on female violence, female on male violence. There's a lot of it. Violence being casually thrown around is a problem that society has to confront. You're always hearing in the news about some new horrible violent crime. People need to get more civilized.

As for specifically male on female violence, I've got a cousin whose husband put his hands around her throat. He also had a thing for punching their kids. Luckily she successfully left him and took the kids with her. At first the authorities weren't very helpful but that improved. I'm very glad he's out of the picture. The throat thing is pretty significant, because strangulation is one of the primary ways women are murdered. It was a worrying situation before she got out of there.
