To take just one example, and assuming that it really is terrible to wear socks in a pool (I know that's not actually terrible)... If the sock-wearer were of the same race, would the white person just complain directly: "Hey this is a family-friendly pool: take those damn socks off!" or would the person not care at all because it's fine for white people to wear socks in the pool? The two possibilities both have racist implications, but different racist implications. I almost feel that in the first case we all just need to get together and talk it over. In the second case the racism is fairly irredeemable...
