I'm sorry Dick, but I feel you are missing the point. I don't disagree with you and your points about the songs.   But that is not the point of this issue. There is no reason to make children pawns in a silly battle over definitions and politics.   

Because you are uncomfortable about a song NOT being sung, a child should be made to feel uncomfortable by having it sung? I think we are all a bit older and wiser and can understand reasons, but why make children suffer?

The bottom line is, the song was NOT censored.   The song is still available, they just did not sing it in their concert. That is NOT censorship,that is common decency. The school still discussed the issue and did not hide from the facts.   Singing the song would serve no purpose.
