It's a combo of nature and nurture. Male animals behave differently to female animal, so it will not surprise me at all if someone can produce some research that shows that children raised in an entirely gender neutral environment end up with, on average, slightly different traits depending on if they are girls or boys. Someone upthread made the point that the biological role of women probably predisposes us to be more nurturing.
Doubling down on this is the role of society. DH nearly lost his shit at a swimming pool once, when a stroppy little boy barged one of our DDs out of the queue for the water slide and his mother, rather than sweeping him round to the end of the queue with a few admonishing words, just said, 'Oooh, boys will be boys.' DD1 had a real moment of glory at primary school, and I was summoned in to be told that 'it wasn't behaviour appropriate for a Y5 girl' - as if WAS okay, or at least understandable, for a Y5 boy.
(And, as an aside, think of the shit girls get given to play with. My DDs were not impressed when small by the familial outlawing of Barbie, but they now say, 'God, I'm glad you never let us play with that crap'.)
So... if you get a baby boy who is particularly influenced by his testosterone, and lives in the sort of environment where the adult women are skivvies and the males the lords of all creation, it's not going to be surprising if he has an overwhelming sense of entitlement and then, if his girlfriend, partner or wife doesn't toe the line or act the role, she ends up getting decked, or stalked or manipulated with threats of violence.
Boys will be boys. Yes, they will be, but when that involves them acting like anti-social little shits, they should be gently corrected (and sent to the end of the waterside queue).
