Martin, I think it is mixing apples and oranges.   I don't disagree with you about political correctness creeping in. People need to rely on their own common sense and morality. Screw the doctrine. I just skip saying "under god" if it bothers me.   Loyalty oaths bother me to begin with.

I feel that teachers need to continue to challenge kids to think for themselves and not follow some silly doctrine that has us thinking in terms of left/right.
