I just started reading OB, so I am not sure if I am a rationalist by this blog's definition. However, I do try to be think about my decisions and pick the rational choice.
I grew up in an accepting Christian family where discussion was encouraged, instead of being indoctrinated into a religion with little room to question.
I have now evolved into believing in the idea of good and of trying to do good. In my mind God= good, therefore I believe in God. This idea fits into several religions. In context of Christianity, the main point of dissent is Jesus. However, I believe in the idea that we are not perfect and can be more good than we are now. This is the idea behind redemption, and the idea behind Jesus.
I share these beliefs with those who ask my opinion on religion, but I don't participate in these types of discussions with extended family because I want to love them in the short amount of time I spend with them, not create conflict.
In your own family, however, you can create a safe environment to question anything and everything. Discussions like these can refine ideas and the ability to communicate ideas. Both of these things are valueable for all parties involved.

I have OB on my regular RSS reader, and I consider myself a fairly spiritual person.
One can have religion and still think deeply -- the thought provoking discussions and posts are intellectual fodder for both atheists, agnostics and religius people.
Why is overcoming bias equivalent with being atheist or agnostic?
