Why

When we teach young men to be violent, through sports, in the military, playing video games, watching movies and TV, etc., and we teach them that women are just objects to serve them, should we expect anything different from them when they react and beat women, especially those close to them?

When their first reaction is violence, why do we expect them to think and act differently when we've taught them not to think but to just react and to react with violence?

When we teach them to only see women as objects, the same as those we teach them to hate and act against with violence, why are we still surprised when they prove we taught them well? 

And do we actually think we can unteach them what we've taught them their whole life?
