Seems (english perspective rather than american here) that the majority of race-offense related to blacks is taken in fact by 'upper class' white people with a race-complex verging on obsession who just want an excuse to act like a bitch and cry racism on the behalf of others who probably either would never have heard the remark or read the allegedly offensive material in the first place, or if they did then wouldn't have a single spare fuck to donate. In fact there are 'JOBS' and I use the term with both the greatest reluctance and the most gigantic serving of vitriolic sarcasm as is possible to emanate from a mouth without spontaneous human combustion occurring on the owner.
Basically (often white) sacks of dog shit that collect a paycheck to take offense at the most innocent remarks of a non-racist nature that any ethnic minority would probably not even notice, and break down in tears in shock and 'offense' on behalf of whatever ethnics the remark or literature (was possibly purported to have) involved and if they did notice then they wouldn't likely have given a fuck about.
IMO such 'people' who get paid to cry racism and in the process ruining the careers, and lives, and reputations of the innocent, ought to be burnt alive and before they die, but once their skin is all burnt off, salted with caustic potash.
