GBV is more than just actions, it is also a huge culture around being "manly" to the point where it is seen that you need to dominate multiple layers of society, ie control your woman, control your home, control your children.
It also leads to a habit where many men want the toughest of the tough, vicious dogs, big cars, tough activities, etc.
It is reflective on this very forum where some forumites feel like gatekepers of the sex, proclaiming "they're not REAL men", threatening violence against anyone they disagree with as if klapping someone makes them correct.
There is also a habit to associate negative traits with the female sex, feminine nouns and adjectives are associated to people who they dislike.
So it isn't just violence, it is a whole cultural shift around that it is important to be the manliest man ever, and some people intepret that in different ways or else their identity feels threatened. We can't even joke about sexuality without some people feeling insecure.
