*eazybee" said "Male violence is an expression of contempt for women, compounded by rage, fear and physical power." I think what some fear is their own need for women. As "real men" they expect to be autonomous and independent, free to carve their own path, dependent on no-one. To be so reliant on the goodwill of members of the smaller, weaker sex to satisfy their deepest desires, and have to give up some of that independence and admit to their need is frustrating to them.
So they frame it to themselves (perhaps unconsciously, but some quite openly rant about women) that the women are at fault for not being suitably servile about providing wonderful meals instantly on demand (as their mother did when baby was hungry) or for wanting to have a say in joint decisions, or just for being attractive and making them feel horny but not being willing to have sex, - and they must be punished and forced to obey.
Other reasons are not the root cause of the violence - many other men drink alcohol, are unemployed or poor or uneducated, are of various races, or have some other second reason to possibly feel animosity toward women, but never resort to violence if they don't have that basic resentment.
