Interesting findings

While reading today, I read that the people in the football gangs pretty much regard the games as a religion.  They are practically a cult for their team.  This could potentially be the reason for the gang in the first place.  I do not know exactly how they started quite yet as I am focusing on the "what are they?" question.  They also see the violence as good and the police as bad, which is quite the opposite of the normal citizen's view.  I still don't know why this is, but I will find out.
