Jade Goody's dead

Yes but you said it makes the line blurry. It doesn't. All it means is that the person has racist thoughts in their head, but in normal everyday life they manage to conceal them. However, when they get pissed off and all riled up they can't control their feelings and the first thing that comes into their head comes out of their mouth.

By today's PC standards I don't believe that anyone at all is entirely free of racism, whatever their colour. Assuming that we're talking a sliding scale here, from black to white and every shade of grey in between.
