I'm not saying it's right, just possible... From other threads on here it seems as though some don't believe it is, and that racism is simply a black or white issue (pardon the pun)...
For instance, if someone says "he's got a fiery temperament, but then he is Italian", it may be a lazy stereotype and therefore racist, but surely it's not in the same league as "I hate all n**rs".
Should both be regarded as equally unacceptable as racism is racism full-stop, or is it reasonable to shrug your shoulders about the former and not cut them out of your life on account of their prejudice?
