A powerful video from The Last White Man, the reborn video channel formerly known as VertigoPolitix.
The basic gist is this: people that have proven over the course of millennium that they are incapable of creating functional societies cannot be absorbed into existing civilizations and sustain them. Replacing Germans and Frenchmen with Somalis and Eritreans is not going to result in a more diverse Europe, it will simply result in Somalia and Eritrea with snow.
Watch and learn.
