I try not to mention it because it always comes across as though I'm painting myself as a tough nut when really I'm a bit of a coward trying to escape the introvert in me, but I've had a few fights in my time for sport (let's say I have a mixed record at best), and for me hitting someone outside of a ring, or away from a mat, makes about as much sense as slide tackling away from a football pitch. And, honestly, maybe I was lucky I was involved in that kind of sport from a young age because it can be a lot of fun, but it left me with no desire to be an idiot outside of it. I've seen a fair few bloody noses, more than one broken arm, knock outs, dislocations, and that's in controlled environments. Fighting's dangerous. Just last week there was a story in the news about another death from a single punch to a shop owner and all over some rizlas. Some sixteen year old's facing a murder charge because he thought you could hit a random guy without consequence like in a cartoon.
I honestly have no problem with anyone who enjoys a good scrap, it's just there are so many places you can go and find a willing participant, matched up for you so it's a level playing field, and not spoil the streets for everyone who doesn't want to be involved. But that's not really what attracts people to the hoolies. They want to be in a big group, they want to be the big boys in the playground, and they like intimidating people who want no part in it.
