I do think there has been an increase in open racism, but I think this is mostly down to the imported American style race politics and the way the left has embraced this. The same thing is happening in the US.
On the one hand there is the immigration question, and then added to this is a lot of new messaging that is very contradictory to the way issues around racism were treated in my youth. Which was, we are all human beings with a cultural and family background, some shared and some not, race is in itself not something we should be using to give or take away privileges or status, with a fairly broad approach to history and understanding of human shittiness.
Instead now there is what the Americans call "antiracism" as practised by people like Ibram Kendi, who says that the remedy for past racism is current racism, or that silly woman who says that "whiteness" is something that needs to be repudiated and destroyed. Weird stuff like what happened at Evergreen college. Lots of focus on "decolonising" which is often completely meaningless.
Even my kids who are fairly "woke" say that they think that it's being so emphasised in school that some kids, particularly the boys who want to rebel, and latching on to it simply because it seems like the main thing that the authority figures care about and are constantly talking about. Even among their friends it's become something they seem a little cynical about, which is totally understandable but I can't see it as really positive.
And the worst element of it, imo, is that to a large degree this seems to be a kind of proxy class war - it is middle class professionals, of all races, using it all as a stick to beat working class and poor people for having the wrong kinds of interests, language, and political concerns - like the effects of mass immigration on wages and services. Some people on the receiving end of this see what's going on and react to it for what it is, rather than thinking it's really about all that other shit. But the fact is that a lot interpret it as being just what it appears to be, a heightening of racial rhetoric, and an attack on who they are culturally and ethnically, and that's how they respond too.
Lots of people saw this for what it was when it started, and pointed out it all ultimately would play into the hands of race essentialists and old school racists, but the stupid middle class progressive left were as idiotically blind as they have been with gender ideology. (which is another version of the same thing.)
I understand why your worried OP. I think the best thing to do is not to get caught up in the proxy war, instead, fight against it at its roots.
