It's too late now. Western Europe is destined to become Islamic/African countries. Nobody to blame but yourselves and even now, with all the grenade bombings and gang violence, all the welfare leeches, the low test scores, the high rates of sexual assasults, the majority of your people support welcoming even more.
It's some kind of brain dysfunction. Even Western European who move to 3rd world countries.. they LOVE the "culture" and don't see a problem with the crime, corruption and the dirty streets. If they don't see a problem with countries like that, then they won't see a problem when their own countries become 99.9% Middle Eastern/African.
