It isn't really that radical, given how most Islamic countries as well as Islamic immigrant communities within West are mentally stuck in Middle Ages. Nothing to do with poverty either - plenty of Gulf theocracies are quite rich thanks to fossil fuel exports, while most Muslim communities in Europe are privileged in many ways.
Nice strawman, bro. So far we see the exact opposite - anti-nationalist forces have always been destructive and strictly serve same rich elites that marxists claim to oppose. It is a good thing that both anti-nationalist ideologies (globalist liberalism and marxism) are dying out, while pragmatic nationalism is steadily growing in support across the Western world.I dont buy the idea of a racist nationalism, the idea of the Christian occident and the French people on the one side and Islam and foreigners on the other, this opposition between friend and foe. We already know how it ends, the idea of a "Europe of Fatherlands"
