They say stuff like "rules, naah" and "my parents are ace trainers what goody two shoes" like what the heck? Just because they cut their hair in that way and dress like that doesn't mean they're bad people? Are people actually hating on people who want to look different so they portray them badly in a game?

They replaced the roughnecks/bikers with the punks as the token THUG trainer class, that's why. The klink shirt is so awesome though, sucks you can't wear it.
Most of the punkers I knew growing up were pretty cool actually, nicer than the gangbangers/wangsters TBH. Some of the girls looked like methbuckets(and yeah they did drugs for sure) but this one I knew was one of the coolest girls I ever met.
