The harm of Atheism is that it's an approach to life that cuts you off from God, which has unlimited negative consequences, even if we can't see them.
Being blind to this part of reality which is much more real than this one (and dismissing everyone who aren't as superstitious) doesn't make someone enlightened. It just makes them spiritually blind with all that it entails. You don't get knowledge of these things by examining physical evidence.
Organised religions has nothing to do with it and has never been my focus. However, it's also possible to become enlightened through a manistream religion like Christianity (there are many examples of it). And there's no reason to focus on crucades and percecutions that happened centuries ago. That has nothing to do with the things of value someone might take away from Christianity now.
