You’d need an awful lot of people to bump that 19% up to “40-50%” and I’m fairly sure that if I went to Germany right now, and we’re on perception alone so it’s gunna be pretty racist, I wouldn’t see one person of colour for every white person.
I live in an international city and it’s still mostly white people here despite seeing many definite immigrants all the time. They just stand out against what I was conditioned to believe is “normal” but that’s it.
It would actually depend on where in Germany you are going, but since the first Turkish "Gastarbeiter" (among others, quite some nationalities) came to West Germany over 60 years ago, it is not uncommon to meet people of Turkish descent there. (East Germany not so much, they had Vietnamese workers but mostly deported them back to Vietnam after the re-unification.) Combine these Gastarbeiter (and the three generations after them) with a declining native birth rate and an influx of asylum seekers, and it could well be 40-50% all together.
The big question is what the problem is here, and the answer is that the far right wants it to be a problem so they can come to power. So they'll bloody make it a problem and try and sabotage any solutions. These last lines are my personal opnion obviously.
I think they’re saying that children who are born in the new country should be counted as foreigners. Which is kinda fucked up but yea I don’t think they’re saying that children moving to a new country aren’t counted.
