I don’t think Europe or really anyone else has an answer for their societies being invaded and overwhelmed by third world immigration waves (largely Islamic) with values averse to Western culture.
This will destroy the societies they invade, of course. And I think Western civilization is worth saving. Both for selfish reasons and because it’s a damn sight better than scrabbling around in the dirt with sticks that Islamic culture will lead to for the foreseeable future if allowed to fester.
Fascism doesn’t work but liberalism also does not work. It invites the infection in. So…what now?
