Point is, "Spike", you said a dumb thing, then tried to back that dumb thing up with anecdotal evidence from your apparent life in a godforsaken hellpit, where hope dies and love cannot escape. Which smells a lot like middle-class bullshit to me, anyway, but that's beside the point.
Are there gangs? Sure. Are there crazy religious movements? Sure. Do people flock to where they can feel like part of something? Of course. Is this something that is in any way, shape or form new and prophecized by fucking Akira? Oh, hell no. Do you even read history books that? And I mean real history books, not romanticized nonsense about feudal Japan.
You'd probably balk if Bob or I did really say that the world was just like the Warriors now, or RoboCop, but that's exactly what you're saying, because you're applying the very common gang-dystopia theme, a fairly generic cliche springboard in a lot of sci-fi, and supplanting it over society as a whole, and that doesn't ring true at all. So if your stories are true, then I suggest you move, because you live in what sounds like the worst place in the Western world. And if not, then I suggest you broaden your horizons outside of your starry eyed fascination with Asian action cartoons and videogames a bit.
