Amazing point I just read in German on LinkedIn:
Paraphrased translation:
There is zero evidence that people who are AfD sympathisers will at some point have the feeling: "Ah, now there are enough restrictions [on asylum seekers' rights]. I can stop voting for AfD."
...yes, I guess the Overton window moves over because the center/center-right thinks at some point their concessions will satisfy these people, and choke out the far right parties. Nope.
