^Interesting. Would increased tribalism and religiosity be due to Terror Management Theory?
That could well be. The common mistake that liberals make is that they think the refugees are "better" people, because 1. they are a minority; 2. they went through a lot of hardship and (perhaps) 3.it is a bit romantic to help them. Well, I believe that hardship doesn't make people better, but make them more desperate instead.
Last year we imported more than 1 million refugees in Germany. That caused loads of social friction, because these refugees came from backward cultures, where humans-, women-, LGBT- and animal rights are practically unknown. The refugee's expectations were also set too high, because they were promised houses, money, cars, loose women, etc. for free.
