In Ireland knacker almost never means a member of the traveling community but that is the origin of the term. It is a word I don't use personally however because I do think it's a filthy word but his use was no more racial than if he'd called her Asian. The putting down of Americans in the last CBB was a lot more racially charged, as is forum members dropping Marc's ethnicity in insults towards him (vile Irish womanhater etc). Though the contestants in CBB were using more PC language. I think it's a question of context though I wouldn't justify him saying it since I dislike the word myself.
