Yes, racism is everywhere, but your story sounds a little fishy. I don't think you can ever be more than 20 feet away from a white person in Manhattan, 24 hours a day, and that's including Harlem.

More to the point, in a city where there's tons of diversity on every street corner, there might still be some racists out there but you can guarantee their racism is just making them miserable every day -- most of us enjoy the diversity.
