Deistic or Theistic, if someone doesn't suck at religion I think that they should be left alone. Especially if that leads them to give money to the poor, teach in developing nations, etc. While it can be argued that those things have negative effects I've also seen some of the good that comes from it first hand.
I love this comic. I believe it sums up most of what I think about religion. The only thing I would change is the one where the father is teaching his daughter. There does need to be room for a parent to "express" belief to his children and acceptance when the children differ from the parent.

Agnostic and atheistic beliefs can be added to the above comic as well. :-) That being said, if you see someone sucking at their religion please school them and tell them I'm asking them not to make the rest of us look bad.
