Doctrine of atheism WTF?

[TheoneandonlytrueGod]

I think dictionaries are not always helpful because they only represent the viewpoint of whoever wrote them.

By doctrine, it could simply mean a set of reasonable arguments some atheists adhere to that make belief in god unnecessary and irrational, it doesn't necessarily mean it's a doctrine like religion is.

Thanks Dystopia that seems to be the best answer yet.
