Maybe you will be less ranty about the black American thing if I can make myself more clear. Racist people in the US have suggested that black people should "go back to Africa" for longer than I have been alive. You are suggesting this will become part of the mainstream discourse in the US, but I don't agree. Maybe I don't understand who you mean by mainstream? There is talk in the mainstream about rejecting critical race theory, because it is racist!
Because I’m not suggesting that. I’m talking about when people say a particular group of people is the problem. When they get blamed for the things that are wrong with the country. As we are increasingly seeing about immigrants, Muslims, and other minorities in the UK and elsewhere.
Not very long ago in the US it would have been perfectly normal to tell your white daughter to stay away from those dangerous colored folk. Before the civil rights movement, many places had racial segregation laws. Even when I was at school in the UK, causal (and not so casual) racism was everywhere. Jokes about niggers and pakis were common.
It wasn’t even very long before that that a country blaming all their problems on another religious group went very badly for them.
Things did improve over the last few decades. Attitudes gradually changed in the US and in Europe. New laws brought in to guarantee people’s rights. For racial minorities, and also for women, gay people, etc.
Then a little over a decade ago, we saw the emergence of the alt right (new right, radical right, whatever). Mainly angry white dudes saying that all this wokiness has gone too far and that really it’s them being oppressed. Saying all the things that had become a bit taboo and normalising much of it again. Arguably Gamergate was the first notable example hitting the mainstream (sort of mainstream).
Nothing is guaranteed forever. Any progress we’ve had over the years can be undone if we let it happen.
The US is currently not a shining example of “it couldn’t possibly happen here, we have checks and balances!”
Okay, maybe I misinterpreted this part of your post -
The real point though is about collective blame. It’s become acceptable to brand all Muslims as a threat. Something that I don’t think has hit the mainstream discourse about black people in America yet.
There was a time, probably the same time it was happening in the UK because even though the internet didn't exist our cultures still overlap (even if they're not exactly the same), when racism against black people was the norm. They were segregated, they were viewed as a threat, and viewed as having less worth than white people. I think both our countries have come a long way in rectifying that, but I agree there can be backwards steps, and flare ups of the old racism and racist language.
I don't believe that branding all black people as a threat will go mainstream, or at least not any more mainstream than it already is. A few months ago there were lots of memes and videos discussing "black fatigue", including from many black content creators. This was a reaction to some viral... I don't know what to call it, maybe misbehavior? Antisocial behavior? Criminal activity? Because it was both, sometimes just bad behavior, but sometimes crime like vandalism and shoplifting. I became aware of it after Carnival Cruise Line changed some of their rules to stop some bad behavior on certain cruises, like banning "clack fans", and loud speakers, and some other things I can't remember. There were videos of the bad behavior online, and that is when people started making "black fatigue" content. Now there are "teen takeovers" which I think something similar happens in the UK, where a bunch of mostly black teens takeover some place and smash and grab stuff from stores. There's a problem with law enforcement in some places that refuse to do anything about it, and you'll see it is worse in those places, but practically non existent in others.
I followed Gamergate. That was insane (but also fun to follow. lol)
I think one mistake you make is assuming everyone anti woke is far right. The term "wokeness" doesn't have an agreed upon definition, but imo it is a combination of critical theory and signalling your agreement with critical theories. I'll use upper middle class people as an example, they will promote things to signal they are part of the group, despite the consequences of whatever it is they're promoting having no effect on them personally and refusing to consider the bad effect it has on other people. Or they will say it is some form of "ist" to even discuss the bad effects. So, there many people of varying political ideologies who oppose that kind of wokeness.
I should say "woke", is not the same as "stay woke" from the Black civil rights movement. It was co-opted by other people, but those (mostly white) people pretend it is racist to be "anti woke". They pretend to not understand that the word now encompasses something different. Most people, if they read it, will reject critical theories, which doesn't make them racist, but most people aren't going to read past the blurb to find out the details of the theories under the critical theory umbrella.
