oversensitivity at its height, i think.
there was episode of "Curb Your Enthusiasm" awhile back where larry is walking down the street humming a tune by Wagner and he gets accosted by a fellow jew who angrily exclaims "You have forgotten your Judaism!" I think this situation, like the one on the show, is another case of people who need to just get over it and accept the music for what it is: beautiful music.
