football matches. Mind you, some would say the last one is a religion

Oh, I think calling it a religion is understating it rather a lot (aka huge). It is tribal, it is cash cow. It is politics so much that colour-blind prime ministers have to avow to like West Ham, when they mean Aston Vanilla ('cos they're easily licked).
Presumably prime ministers are so called because they only see in primary (political) colours!

And if we are talking abuse, why does blame for disasters at football stadia fall solely at the feet of those sorting the mess? Answer because anyone pointing out "this or that measure was the solution to crowd behaviour" is roasted by the fans. It is easier to name a scapegoat than blame a mass of human lemmings. Distasters rarely have a single contributory cause.
