I've never been, either, but I have lots of friends who are rabid college football fans. To a person, everyone of them who had been to a Hurricane home game rated it as the most hostile place they had gone. Like an Oakland Raiders game, apparently.
From what I hear, you're right that our bad behavior is nothing compared to the English soccer fans, although at least a couple of Dodger fans must have been taking pointers from the English fans when the beat that Giants fan into a coma. I hope they put these guys in a cell and throw the key away.
And it’s not just the Brits. They just happen to get most of the bad ink. The Dutch are pretty bad and the Italians are barbarians. My sons and I were leaving the Stadio Olimpico in Rome one afternoon. One of the local teams, Lazio, had played and were beaten by AC Milan. There was a Mercedes in the official parking lot with Milanese license plates. The car had been totally trashed by the Laziali.
