Is it perhaps, that as a society we have created conditions that have marginalized too many of our men, leaving them with devastated self-worth and feelings of failure? With so much pent up rage and denied accomplishment placed in with the hormones and sexual drive of men should not be surprising to anyone that there would be a natural tendancy to lash out...
And I would hardly be saying just our society - no society has ever been perfect - and these conditions have to have existed in each of them.
I am not excusing the behavior. I think rape is almost worse then murder - the victim has to live on with the memory of the event, producing effectively infinite torture. My point is more towards, are there possibly root causes that extend beyond the traditional radical feminist labeling of male-kind?
