I recently left Berlin after over 30 years. I have been outside, but not for long to get to know "other germans". And yes, you are right, the mindset here in the south is a lot more narrow minded and what people say about refugees/foreigners is just mind blowing. Which is kinda sad. I like it here, but I doubt I can live around these people for much longer.
So there's history in Australia of white immigrants trying to force aboriginals to "integrate" with whites. I suppose you could call that "targeted diversification". But you make it sound as if your social circle is white people, objecting to "diversity" in the sense of deviation from whiteness.
Would you mind clarifying?
Well I'm not going to argue with a blood-and-land white nationalist from Oz, telling me how people feel here in Europe. I'm going to butt out, because I have blood-pressure problems. Bye.
Oh, come on. That's QAnon conspiranoid bollocks.

Racial diversity exists. Supporting it or opposing it isn't going to change that.
(As a counter-anecdote, I don't personally know a single person in my social circle, in Australia, who is supportive of racial diversity, ranging from indifference to a depressing powerlessness and helplessness to protest what is being done to us by the government, to open and outright racist hostility to the concept.)
