It also seems it's quite OK now to shout down anyone trying to say that, yes, black and brown people experience prejudice still, by saying "free speech!" or by complaining that as a white person you are expected to STFU and take full personal responsibility for slavery or some such rubbish
I don't think there are many on this forum that actively try to close down, or shout down, speech and debate - except for a few who come on to goad - but never really engage. And nobody is denying that racism exists - of course it does. Prejudice will most likely always exist in one form or another, because people can be prejudiced about all sorts of things. That is an inevitability of individuality to some extent.
however, what is now happening, is that people are using an intersectional framework of oppression, in place of actually thinking for themselves. Not all criticism of someone is necessarily racist or sexist or homophobic or transphobic.....it can just be criticism of them as an individual.
And the problem with blanket accusations of prejudice is that they can be spectacularly wrong. See the short film further up whereby a black female interviewer, unknowingly, accuses a black man of 'white privilege', simply for the reason he is disagreeing with what she says.
And the fact that she based her assumptions of his race on a really quite racist agenda of who she believed should work where, and for whom. In her mind, black men did not work for Fox News - so he must be white.
That is the issue. It does not deal with arguments - it makes judgments based on group characteristic alone.
