I'm sure you're going to find this an odd reply, but what about "Boundaries" by John Stroud (I think?). It is a "Christian" book in that the author is a Christian. But it has alot of good, solid advice about how to lay down boundaries in such a way that other people know when they have crossed the line (if they truly care). I found the book helpful in giving me some tools to let my other fundie family members know what subjects/attitudes I just won't tolerate. And they have, to my surprise, honored most of my wishes.

I don't want to entirely shield my children from fundamentalism because I want them to know how destructive it can be. So I believe the answer is education, not avoidance. But for those times when education involves exposure, I want boundaries there to let others know that there are some lines that just shouldn't be crossed, even if they believe they are doing it in the name of God.
