There's a fine line between communism and integration. Integrating schools was a step in the right direction, although some people deemed it unfair; don't you think that integrating communities would be the same way?
Affirmative action is another way to do this; it is an economic means, and sure, it may sound a bit like communism (although it is clearly a stretch to even make this analogy). I think that affirmative action is good but integrating communities is an even better approach. The goal is to desegregate America, and affirmative action doesn't help much during compulsory education, before college and jobs.
