You know, it's not as much a sleep (passive) as it is an ideology (active) that is based on guilt from WW2 and the nazis. It's kind of a European shame that raised the liberals and communists (Stalin was worse than Hitler, but nobody's worried about the leftists) into power and created this very persistent ideology of multiculturalism. It has no connection with reality so it cannot be argued with rationality, because no matter how much trouble the mass immigration causes, restricting it would be against "human rights", and the problems aren't connected to immigration but social justice. It's pointless to try to argue through all the ideology, because as with religion, you can't use rational arguments to counter points of faith. In reading my own countries (Finland) news today, there isn't a single thing that would even TRY to find anything wrong with immigration policy or Islam itself, but very strong agenda saying that closing borders will help nothing, fear helps the far right (which is the real danger) and these terrorist strikes are the reason why we should take MORE immigrants, because they're running from terrorists. Anyway, they can't lose. Because no matter what happens, it's someone else's fault and there is no problem, and if there is, it's someone else's fault.
