"don't generalise and associate atheism with communism. It's intellectually dishonest.".

No, it's not.

Well, have I got news for all of you Redditors. They go hand in hand.

Communists always enforce Atheism when they take over.

Oh so that's how it works, thank you wise OP for opening up my eyes to the ways of the world now. Alcoholics are almost always adults so now we can say that all adults are associated with alcoholism. Almost all school shooters are white, so now we can say that being white is associated with school shooting. It's a good thing that atheists also don't understand causation, correlation or making good arguments so that you could enlighten us.
