All white people with any sense shut the hell up a long time ago. Not necessarily for the reason you’ve outlined but because ‘racism’ – the concept can now be applied to almost anything. Whatever white people do is racist. Their Anti-racism is racist. The words being thrown around become diluted and more meaningless with every unthinking utterance. Black people don’t have my support. White people don’t have my support. Intelligent and insightful people have my support regardless of their skin colour. At the moment there’s very few insightful people and far too many echo chambers promoting unthinking idiocy of all flavours.
