Repeat after me: "Immigration is good. There is nothing good but immigrants. Multiculturalism is the future."
It's not immigration that is the problem, but rather groups of immigrants that do not assimilate into the society they move into. Not a healthy thing, and will only eventually lead to factionalism.
Europe's self-imposed quicksand is gurgling at it's peak and is about to swallow the fools that brought it about. Too bad that others will suffer also.
