Michael Richards publicly apologed via satellite on the David Letterman show last night. I personally could care-less about his poor attempt to save his D-list career. People in "Hollywood" use the word apology so loosely.
In Hollywood, the word apology means: I'm not actually sorry for my actions, but I'm sorry I got caught. Therefore, in order to save my raggedy ass, I must issue a false statement to the public by placing blame on someone or something like (substance abuse, poor childhood, being molested as a child, etc). Michael chose to blame Hurricane Katrina for the cause of his "hate and rage."
According to TMZ, he apologized to the people who took "the brunt" of his abuse, saying he was "really busted up," but then went on a strange tangent on race relations, saying he was "concerned about hate and rage" and about a "great deal of disturbance between blacks and whites" after Hurricane Katrina.
