The religion of football breeds the violence of hooliganism. The religion of Charles Manson led his followers to murder Sharon Tate, et al. The religion of nationalist bigotry led to centuries of violence in the Balkans. It's about people, corrupt and fallen, doing their thing; if "religion", the political entity (which is the real culprit here, and only as good as its people), divorces itself from its spiritual technologies (or has none), Bad Things® will happen.
