(At the South by Southwest Music & Media Conference, Asleep at the Wheel co-founder Ray Benson defended the Chicks: "I applaud the Chicks for saying what they believe. If radio stations think they need to censor musicians for their political beliefs, those stations should move to Iraq.")
The stations are responding to their listeners, not censoring. If the DC were releasing an anti-war song (can they beat Madonna?), and stations refused to air it, that would be censorship. If Maines called in for some anti-war chat with the DJ and he refused to put her on air, that would be censorship. This is just part of a free-market economy...businesses acting in their own best interests, and giving listeners what they want and deserve ~ the same freedom of speech Maines so enjoys.

Censorship? Hardly. Such a much-abused word. As you yourself said, the stations would be "responding to their listeners, not censoring".

Governments censor. Businesses make business decisions. For these radio stations to be practicing true censorship, they would be able to enforce their no-play decision on all media outlets, on threat of violence.
