If you're in Europe [...]

Germany, Ruhrgebiet. So a region that has been shaped by coal and steel industry. Though it's one of the examples where the change from heavy industry to modern economy worked out relatively well. But that means we've had lots of immigrants come here to work since the nineteenth century. I always like to think hating on immigrants is like taking a crap in your own backyard. Because that's my heritage and part of what constitutes this region.

Of course it's way more complicated than that. Sometimes we forget where we come from. And it comes with different implications when it's been Polish immigrants who are catholic as well, or Turkish people who grew up with a different prophet. (And they do weird things like go to sunday school on friday, or take off their outdoor shoes before prayer.) And after that (in recent times) it's been other countries like Syria where people came from due to war etc.

I suppose there is a parallel to the USA. US history is a lot about migrants, let alone a few Native American people. But that was a long time ago.

your country has a thriving right wing movement

Yes. That's something we all struggle with. And it worry about that. I think there is a multitude of factors. Society should put in some effort to fix this. We have stupid people, people who aren't stupid but easy to manipulate, we have people in precarious situations and it's not healthy to leave them behind. Especially without any perspective but with access to Telegram to radicalize themselves and each other. I'm not surprised this turns into hatred against random things. Immigrants, the establishment, ... I suppose that's a big reason why we have some 20-30% of people voting for some complete nutjobs. But: It's a minority here. And that's (still) a big difference to the situation in the USA. But we also have a lot of the same problems. And I suppose another thing is the world getting more complicated and people having to deal with it. They're looking for answers. And if we don't have any, someone else will make up some simple answers and hand those out to everyone.

I'm making a claim about the human psyche, not ethnic differences [...]

You're right. I'm reasoning about things and none of that is about thinking. It's about emotions and feelings, wanting to be heard or a lack of (felt) perspective genuinely turning into hatred. It's all about human psyche and manifesting in a very, very unhealthy dynamic. I wish us all the best. And I really hope there is a way to reconvene and steer towards a future that's not dominated by hate and small-mindedness.

(Edit: And btw, my perspective doesn't translate to other parts of Germany. It's a whole different story there. And people might not even have any immigrants as neighbors if they live in other parts of the country.)
