Well, this article seems to have brought out the pretentious wanker in a lot of people.
How long did you have to spend in that cheap art college so you could come up with reasons like "It's nature, not nuture. We humans are just violent disgusting creatures"? And let's not even start on the 'experts' who have 'done real research'.
This article doesn't state "all British schoolkids are punching each other" and I suspect, as has been the case many times before, it's a small group of kids in a few schools who took the game too far and now it's becoming a national emergency because of an isolated incident. It's like British Bulldogs. Yeah some people muttered under their breath about it, but SOME schools only began banning it after one pupil suffered a bad injury(a couple of decades after it became popular). They were still playing it when I left school 8 years ago.
Kids have always emulated things and very few of their schoolyard games draw attention. Video games are just the in-thing to blame today because it's convenient. To be honest, it wouldn't suprise me if there were 'P.C' issues in there somewhere.
Look at the little scrotes who pass the time by drnking cheap booze in a bus stop, heckling pensioners. Or the pricks who go out to pubs JUST to start a fight with someone different to them. Or the 7 years olds who run out in front of vehicles just so they can shout "watch out you fucking ****" at the driver. Now go look at their parents and the homes they grew up in. My old man raised me to respect people and know what the limits were and all the video games I played and violent films I watched didn't hinder those lessons.
