My son had a friend when he was about 6, this kid was to say the least ....an A+ BUTTHEAD. His Mother defended all his actions as "peer pressure" and he was acting out because of society.
He decided he was going to pick on my daughter. He wouldn't stop, my son asked him to stop or get his butt kicked. Well he didn't, and my son lit into him, pounded his face into the driveway. He goes home and tells his Mom he was attacked for no reason.
She came stomping over to my house screaming, I simply looked at her and said, my son's actions were the result of a society gone bad and my son had succumbed to peer pressure. I never heard from her or her son again.
