I think it's unreasonable that women are somehow expected, as a general heteronormative baseline, to be gentle and not use violence, whereas for men violence is just "part of male culture." Fuck that. Violence is terrible, but it's also the birthright of any animal trying to defend itself. Nobody should feel in any way ashamed or shy about using as much violence as they need, if they have no other options. No human should ever feel safe hurting another human without fearing for their own safety, and the fact that some boys are raised to be men who feel that way is appalling.
