That's anti-semetism rather than racism. On a serious note, the saddest thing I ever witnessed was about 20 years ago on the terraces when the more moronic element of fans made 'monkey noises' whenever a particular opposition player had the ball. The irony was, one of our best players at the time was a young black chap; even more poignant was that a lad (about 12) of mixed race heritage was joining in the chanting.
