Have you never heard the phrase 'virtue-signal' or 'virtue-signalling' before? It's been all over FB for the last couple of years.

Basically, it's about people - usually White and middle-class, who ostentatiously parade their political correctness and progressive ideas. When it's safe to do so, of course. A lot of the HP fans who jumped all over JKR when she made those stupid remarks (she's not a very bright person) were virtue-signalling, as were the HP actors and other authors who attacked her.

One of the keys to structural racism is that the powerful who establish and encourage it are not themselves racist (any more than the Pope is a Catholic). They have equal contempt for everyone. But if they can persuade the poor majority that a certain minority is worse -or worse off -than they are, it keeps them in line. Either through relief, or fear that if they make a noise, they'll get the same treatment. In either case, it keeps the poor hanging on in their shitty lives -as long as somebody else (eg PoC) is worse off, they're safe!

Did you actually look 'wanker' up, just out of interest?
