An interesting clip, especially the assertion that accusations of racism are losing their potency. Perhaps people are tired of political correctness, tired of hearing the same old mantras over and over again. Perhaps people are well aware that far too much of it is wildly exaggerated or simply untrue.
I'm not so sure though. We should not mistake the extremes for symptoms of a potentially fatal malaise. Finger-pointing is infinitely flexible, infinitely resourceful, hugely appealing to human vanity. That's one which isn't losing its potency - vanity. Just the opposite as far as I can see.
