Although I modified his statement, he has a point. It's this:
America is actively involved in the Middle East primarily because of economic purposes (i.e., they have oil). Why the hell else would we be involved in that **** hole? Freedom? Maybe, but not likely.
Now, imagine you're a Saudi, or an Iraqi, or a Syrian, or an Iranian, etc., and you see some outsider coming into either your country or what you consider your "domain." You would probably react with skepticism at the least and perhaps even violence in the most extreme. Hell, many Americans get upset when signs in our country are printed in English and Spanish (forget about actual foreign influence, like the govt. of Mexico coming in and trying to sway our politics/economy/etc.)
And then, after considering this, consider that mouthbreathers in that part of the world (due to lack of decent education) make our mouthbreathers look like a bunch of Steve Jobs.
And there you have it. That and the fact many of them (enough of them) still hate us because we're not Muslims.
