Is Religion a Religion?

Questioner: Is it correct to say that ideologies like Marxist, Nazis, Hegelianism, etc. are religions? I think we first have to think about what it is that makes a religion a religion. And when you compare the source of knowledge that religions claim versus let's say the source ofknowledge that Marx is claim, there's a real difference. It's mystical because it's not based in actual logic. But Karl Marx's Marxism allows for contradictions and transcendence of countries called dialectical materialism.
