Good question. I am not going to defend what this guy said, however, Republicans always end up apologizing and/or getting diversity training. Democrats and liberals tend to say that Republicans don’t understand humor and satire and can’t take a joke, and NEVER apologize. David Letterman’s apolgies were pathetic.
Guess what, Dilbert; If I ever become a public figure and then say something deemed “awful..gasp” by the PC crowd and they demand me “apologize”: I’ll tell them (1st Amendment) free Speech, and ‘shut-up’ and won’t do it (mind you I won’t be a jerk and say things that are unkind intentionally).
