"Culture" is way too broad of a term to use here. What one person sees as culture, another sees as stereotype. Someone who's lived in Milton, FL his whole life would view American culture as one thing, and may not even see someone from big-city New York as being part of his culture. Middle-class folks in Turkey, for example, may see the religious-party in charge right now as anti-Turkish. Good luck having those two types of people in the same room together, let alone associate themselves with the same "culture". The same can be applied in Afghanistan, or anywhere else.
Part of the problem with trying to compare morality between "western" civilization and "others" is that there are legitimate historical and socio-economic differences between those cultures. Why don't the lunatics in the Westboro baptist church go bombing funerals, instead of protesting? Why don't fundamentalist anti-government types frequently go around shooting mailmen or state-workers? It's a question of economic status and cultural psychology.
They don't do it, at least partially, because there is too much to lose. Yeah they might get mad, go make some noise, go protest, etc... but most of them aren't going to go blow up an abortion clinic. Having the ability to adequately feed your family, economic stability, and a political system that allows for relative freedom and legal protection, means these people have less of a need to make extreme statements. A suicide bombing, or taking up arms against an invading army (which is how many Afghanis see us), is extreme. They have less to lose. Their societal structure, for lack of better words, sucks. There is a shitty government that can't protect its citizens. There are foreign soldiers on their lands. There is no money, no stability, no certainty. They're pissed. It wouldn't take a lot to push some of these desperate people over the edge. Hell, I'd be pretty damn tempted to fight if we were invaded by China, no matter how shitty my neighorhood was.
Is our society better than theirs? Is our culture superior? I don't know, but I sure as hell would rather be here. But think about what it'd be like if we grew up in the environment they did. It'd be a whole lot harder to stand a moral high ground. I'm damn proud to be an American, but I can't imagine what our people would devolve into if we lost everything, were invaded by a foreign power, or *gasp*, god-forbid, lose the internet or our iPods. I wouldn't trade being American for anything else in the world, but even the most "civilized" people are capable of devolving into animals under the right conditions.
Red Dawn? Fallout? That's what some of these countries are like overseas. Life would suck pretty bad. Where's the vault?
