Ah yes, the gentrification conundrum that keeps liberal heads spinning. Whites were racists when they moved out of the big cities, and now they're racists for trying to move back in. Liberal "logic" at its best .......or worst.
You forgot -- they're also racists if they want to stay in the suburbs away from black people in the cities. So...racist if you move out, racist if you stay out, racist if you move back. Sounds like the definition of being racist is...being white.
