If we do get another world war, which appears increasingly likely, this could finish off what remains of European civilisation for good. But it could also, theoretically, have the opposite effect, where the shock waves could create a different kind of Europe from the decadent, nihilistic Europe we see now. A Christian revitalisation, for instance.

6/1,143 x 100 = 0.524% of Christian vs. Darwin

I am going to assume that a “monocultural Christian Europe” not only doesn’t include Islam but Judaism, atheism, and everything in between.
