Dave, I think that's something you're going to understand better than we too often might here. The simple geography and common American lack of int'l travel hurts us a bit.
England is simply geographically so much smaller. Your communities have to mix more. Here we're so damned spread out that outside the most major metropolitan areas many Americans don't visibly see a significant Muslim presence (for example).
Here we have the significant Palestinian community in the Detroit area and other pockets of population scattered elsewhere. But we don't have the perception of a different community being "everywhere" within the country.
Quite frankly we suffer for that lack of perception. We talk of the "melting pot" but forget that a foreign or immigrant population can't be assimilated or otherwise brought in a culture unless it's engaged. England suffered foreigners of all stripe since Rome and before. Whether they won or lost they all eventually became English in some fashion or another.
You're having similar troubles digesting populations of people now too. It's something we all better do a damn well better job of as the cultures (at least internally) simply can't stay at each other's throats.
