Ill habits of thought for religion

“The original lie is only the beginning of the problem. Then you have all the ill habits of thought that have evolved to defend it. Religion is a poisoned chalice, from which we had best not even sip. Spirituality is the same cup after the original pellet of poison has been taken out, and only the dissolved portion remains—a little less directly lethal, but still not good for you.” (Eliezer Yudkowsky, Rationality)

Interesting, wonder what the Ill habits of thought for religion are (though I can imagine some perhaps)
