As usual, I am not against anyone for making any jokes. All David Letterman is guilty of is being a funny guy, and I don't get where people come off judging comedy within a serious context. Letterman is paid to make people laugh, and he did just that.
However, what I find to be hypocritical is that the same people who jumped all over Don Imus for his remarks are now defending Letterman. I guess it is ok for liberals to offend conservatives, but not the other way around. Interesting.
As far as I am concerned, everyone should shut up and enjoy the jokes. Your moral values mean nothing, and anyone who has an opinion of morality in entertainment does not have a worthwhile opinion in their dumb heads as far as I'm concerned.
