Oh, no! Religion!

Solution: don't take a course on religion. See, I solved your problem. But Christianity did have a bit to do with Western civilization, so you are going to have to encounter it there.

And of course, Christianity is neither collectivist nor an ideology. Maybe you do need a course on religion.
