Not to mention that the entire US is emphatically NOT like whatever he seems to have seen- I can guarantee, for every tough guy you get in Britain, we get two druggie ghetto wannabes who'll bust your jaw open soon as look at you.
It's a big ****ing country, man. Even I haven't seen nearly all there is to see, and I've been all the **** over it. Yeah, there are relatively soft places where your strategies MIGHT work, but there are just as many places on the other extreme, where you're liable to get shanked for looking at some Mexican teen-gangster punk crossways.
Hell, one of my good friends who went to college in Richmond this year, apparently she's heard two shootings right nearby and seen a whole squad of tough guys whale on some poor dude for little or nothing at all. I'm illustrating extremes, here, but it's just to illustrate, since you don't seem to listen when I talk about more normal life. The whole world is NOT a lovey-dovey place. Not for adults, not for pimply high-school teenagers, not for anybody.
