I agree that you should certainly take action to help him understand that it is wrong to single out anyone because they are different. However, i have a vested interest as a "ginger" bloke myself. I never got bullied for it, because i was always bigger than the other kids. For your part, Mum, you can only preach what you practice - "Ginger" itself is a grossly offensive racist label. The pc term is of course "strawberry blonde". And as the wife of any ginger bloke will know, they make the best lovers.
