One aspect of religion is belief in god, indoctrination, and so on. The other is the manual for leading a "good" life - not good as in "approved by god" but as happy, balanced, whatever. I think religion has a lot of experience with dealing with all sorts of challenges in life. I don't necessarily like all the solutions, but sometimes there is some wisdom in it.

I think to get rid of religion (which I would approve of), one shouldn't focus on the ridiculousness of believing in god. One should look at what religion provides to people, and how to replace that with something secular.
