The Enlightenment intended this. The idea was to create secular societies where religion was a minor trivial play thing. So when people encounter ferocious Islam, they simply can't comprehend from it comes. Did not Walt Disney tell us "It's a small world after all?" And everyone is the small on the inside and we should all sit around the campfire singing kubaya?
It is a clash of Islam against Judaic Christian civilization.
I used the term Judaic Christian civilization because it seems to describe the Civilization that arose in Western Europe-- that is the “meme” that was the seed of that civilization.
If the term was coined late, that does not mean it is inaccurate.
