The set of "valid" actions is a superset of what's actually "useful" or "good."

I'm an atheist, but for the most part I enjoyed reading others spiritual practices.

It is useful to learn about others; empathy and understanding are incredibly valuable even if one views the world from a strictly Machiavellian lens (though I hope that folks do not).

There is also much that the non-religious can learn from the religious. What I got from many posts here was a sense of the purpose, meaning, and/or serenity that many of these folks derive from their spiritual practices.

Call me crazy, but those are qualities many of us would like to enhance in our lives. I think there is much to learn from them.
