But that's by far not the worst thing the wrestler, who WWE cut ties with last week, has retweeted, with that dubious honour going to this tweet:
The tweet is a reference to when US president Barack Obama said the word "n - - - - r" during a podcast about racism being alive and well in the US.
Obama's words at the time are perhaps the best answer to the sentiment expressed in the tweet:
Racism, we are not cured of it. And it's not just a matter of it not being polite to say n- - - -r in public.
That's not the measure of whether racism still exists or not. It's not just a matter of overt discrimination. Societies don't, overnight, completely erase everything that happened 200 or 300 years prior.
