In my case because it was a kind of cross between legalised bullying and tribal warfare.
In fact there was something rather sinister looking back, in the way we were taught to view the other "team" as the opposition to be stopped at all costs, just because they had a different coloured top on. Almost as if we were being psychologically prepared to have a "them and us" mentality.
Well I guess promoting a "them versus us" mentality is a great way of preparing one bunch of young men, to be willing to go off and fight - to the death if necessary - another bunch of young men, whom they've never met before, and have no personal grievance against beyond there "Wearing a different kind of jacket"
Looked at that way, 'organised sport' makes a lot of sense if you want to keep things tribal..
