You're sort of describing life as it is in many towns and cities across America. We don't inherently carry racist attitudes around with us, but we just instinctively know the statistics and watch the news... so like you said, we avoid "those areas" of town or groups of them in large numbers. It's sort of like knowing that if you're in a gathering that has a large number of children and drunks, you know they're going to be unpredictable in their behavior. Same with one minority segment of our population... easily offended, irrational and unpredictable, less than average IQ that gets collectively dumber as the numbers increase, and indoctrinated to hate everyone not of their tribe. But life goes on, just practice a few sane behavior traits and you'll probably do fine.
