Yes, exposure, and over exposure is a big factor. Why do you think I object to Mr, son, and grandson watching stuff like Arnold Schwazz, VanDamme, and yes, even Jackie Chan films?

Get exposed to Violence is Virtue young enough, and enough times you believe it. Especially if you are also told all the time that you are unwanted, bad, ugly, stupid, etc. Gangs exist because they provide a secure place to be accepted once you prove yourself. If home could just do that.....
