Actually, most football fans aren't like that. If they were, football would probably end up banned. Most UK residents are football fans, and the majority of them don't act like that - you just only notice the downsides. All the people I work alongside support some football team and they're all respectable people. Most of the people I know in the UK are likewise. Just because a person doesn't have their team's emblem plastered over them doesn't make them a non-football fan. Football fans are pretty good on a whole, but there are those that let them down. I'm pretty sure a lot of bad people in all areas of the world are football fans, they just don't go around wearing the shirts as often.
