But the subcultures in other Western nations don't share the same impacts on other subcultures... at all. That "reverberation" promotes the legitimacy in the minds of young people as they grow. I think you know what I mean.
edit: further, "parts" of the USA, sometimes the parts adverse criminal behavior is actually glorified, are as a matter of fact, just as if not more densely populated than those of other countries.
Sure, you don't hear alot of explicitly violent subculture emanating from Wyoming, but you do from NYC, LA, Chicago, etc.
further further : I know for a fact there aren't alot of young people who say "Hey let's act like a soccer hooligan from Scotland" or like a ... whatever Norway has... but again I'd bet you have young people in your countries who emulate violent gangsters and hate-ridden reprobates from the USA.
