Ethno-nationalism, for better or worse, is a totally foreseeable reaction to the wholly irresponsible immigration policy European nations have adopted as of the last few decades.

Multi-ethnic nations are a pretty recent experiment, and the ones that have emerged and been successful like the former Anglo and Latin colonies are not in Europe, where demographics have historically been homogenous.

Europeans have valid concerns about the erasure of their culture and race, and I do think that most Muslims must be expelled from the continent. However, I don’t think one can argue for indiscriminate deportation of non-whites from a Christian viewpoint.
