It's the first of several topics that Sargon covers here, the article can be sourced but Sargon's take on it is entertaining as well as quite thorough. As expected there is a lot of risible nonsense in there and fishing for this in the SJW world is hardly a challenge any more, but what I'm starting to perceive is a meta-narrative above all the specifics: Marxists know well that any rational narrative can be deconstructed and reassembled to order once one has become proficient at this.. hell they invented the technique. For a while now they haven't been too concerned about constructing rational narratives when nonsense** ones will do a better job of triggering the required response. Sargon knows that humour is the best way to deflate this sort of thing.
Coming back to the UK, the only specific criticism I'm going to offer is about the claim that 'blackface' in Minstrel Shows was a way of portraying "black caricatures", however, anyone familiar with our own much maligned B/W Minstrel Show will know that the characters within were largely singers and performers wearing weird makeup, hardly a racial reference in sight. Maybe it was different in the US, or maybe this statement is simply wrong.
Bringing us firmly back to the UK, his second piece at 9:26 deals with a similar subject but I sense a more sinister tinge to it than the above meme-ing, possibly because this is closer to home for me. Cambridge University are apparently investigating it but I doubt it will come to much.
His later pieces about Corbyn and Venezuela are good, but a different subject matter. Corbyn's response now that he has been 'challenged' will be worth a look, but he may choose not to respond.
** Actually, a mixture of sense and nonsense is usually the most effective.
Searcher(08?) may recognise my use of Sargon here as an invitation to decloak, so he may as well get it over with.
