Swedes and Germans are expected to adapt to predators, but there is no expectation that the predators adapt to decent human behavior? This will not turn out well for anyone involved.
It always seems to work that way—the majority is expected to adapt to the norms of the minority, never the other way round. When I was being trained as a teacher for minority students, we had lessons on how the minority groups behaved and were told to accept that behavior as normal. Fair enough, I was going to be teaching on their turf. But the opposite never happened. When minorities were being bussed to white schools, they were never told what was considered normal at their new school and how they had to change their ways. Any such endeavor would have been considered racist.
