I look vaguely non-white in a way that gets interpreted differently by different viewers, and my personal experience has been that I struggle to convince others just how real the xenophobia / racism of rural whites is, unless they have a chance to witness a specific incident/episode. And I still pass as "kinda white" depending on the viewer / situation, so I can only assume that people with darker or more "ethnic other" complexions than I have experiences that pale in comparison to my own. Some of the same "hey you're not _really_ white, are you?" still happens everyplace else I've lived, but it's friendlier and less threatening in places that I'd describe as "more urban" or "having more economic opportunities."
Just my personal experience, but I fled the small rural white town where I grew up as quickly as I could, and every time I return to such a setting I'm quickly reminded why I left.
