YANBU. My DH is Irish, and has been told he is being 'too sensitive' when he has objected to the 'Paddy' title. He reacted with some very interesting Irish. There really are certain people who don't think it's racist/offensive. They're the same people who call anyone from Wales 'Taffy' and any woman they don't know the name of 'Doll', 'Babe', 'Sweetheart' etc IME.
