I'm not sure about how I feel about Eliezer's approach on religion in the sequences. On the one hand, I like using sarcasm; on the other, that doesn't seem to work for more deeply-rooted beliefs, like religion. I think he should've left religion out of his sequences on rationality and criticized it later. The way he did it, it may scare off people who still have a somewhat deep link to religion, before they can learn enough to be able to break free.

On the third hand, I think I may be biased towards avoiding conflicts.

On the specific point illustrated by the story, as expressed in the quote at the beginning of the post, I do agree. I try to induce that same feeling of "shock from how stupid people can be" when I notice a mistake I've done, as some kind of mini-"Crisis of Faith".

Eliezer makes the same point at If Many-Worlds Had Come First.
