Political Correctness.

Political correctness is not about being sensitive to all groups, it is about being sensitive to "protected groups". For example a radio talk show host in Milwaukee uses an epithet on the air and provokes all sorts of outrage including a letter co-signed by many of our WI legislators. AFAIK he is still not back on the air.

However, a prominent supporter of Senator Feingold calls Condeleeza Rice "Aunt Jemima" and not a peep. Condeleeze being a prominent and solid member of conservative-land does not merit the same protection.
