well nowadays people get more and more violent for no reasons whatsoever , due to the influence of these "mma" and "ufc" crap you see on tv and the internet.
They dont control their frustrations and shortcomings anymore, society ironically promotes the use of violence as a mean to end conflicts even in your neighborhood. Even the 35 + old are sick of getting laughed at by younger unrespectful "kids" who dont give a flying fuck about anything in life.
Everbody's a cagefighter wanabee, so physical encounters for nothing are going to be more and more comon in our western societies, especially with the importation of immigrants who come from tough third world areas and who also promotes and increase greatly violence and the spread of its influence on white youths.
i wouldnt be surprised though that in arab/muslim countries life is less violent and youths are more respectful of other individuals and especially elders. But here in occident, it's changing, people respect nothing and noone, and all think they are as tough as their "hero" they saw on TV the night before...
