I’m obviously not trying to say women are incapable of violence but its a very different thing for violence to be encouraged or acceptable by peers than for individuals to act violently. For instance old social norms from the 50s in American made it acceptable to beat your wife.

Is it a newer thing? Is it more common in some countries than others? I’m in my 30s and I can’t recall this being a social norm when I grew up. I remember men being aggressive with other men sort of being accepted as inevitable but still frowned upon.
