104 Is atheism a religion

Believer says: Atheism it’s a religion because it ends with -ism.  

But skeptic says: Well, the economics of capitalism isn't a religion. And socialism isn't a religion. Artistic realism isn't classified as a religion, either. But all of them end with -ism. While I'm at it, I can mention sexism and autism. They aren't religions, either, although they end with -ism. Thus the guy who says all of the -isms are religions has misspoken himself.

Recap: An -ism isn't always some kind of religion. So it's silly to define atheism as a religion just because the word ends with -ism.
