Look, I'm not saying there isn't friction.

This is quite an unfair characterization of the US. I suggest you read a bit more about the drug running problems on our southern border; border patrol is much less a xenophobic exercise and more of a security necessity. We could argue about the wisdom of US drug policy (and its effect on this situation) but then we'd be getting way off topic. I think its also worth noting that people interacting with the guys with guns on the border are (usually) breaking US law. We certainly treat criminals differently then law abiding citizens.

I've lived in several US cities with fairly high Muslim populations. Hell, I've even seen women in the niqab on US streets. The vast majority of Americans don't give it a second thought.
