some thoughts on religion

When discussing religion with those who believe one sometimes walks a tight rope. When I tell Christians that I'm not sure really what I believe I get this look, that awful look, also one I see when I tell I'm single to a couple. That you'll-get-there-someday look. That I-hope-I-can-convert-you look. It's frustrating because how can I have an honest discussion about this topic when I know the other participant has this alternative/conversion motive. It actually makes me less interested in Christianity, quite the opposite intended affect.
I want a religion that accepts me with open arms, when I'm ready. I don't want to feel pressured to believe every word as fact, especially in the beginning. I don't want to look down on those not in my religion, as those who are unsaved. I want to be as (if not more) accepting of others when I am religious.
It's not that I'm a lazy teenage American who needs a cookie cutter religion to fit my every silly want and whim. I just want to know that what I believe in has been chosen with thought and care. But why do I even feel the need to pick one? Why can't I be content to be a simply spiritual person who tries to understand right and wrong? Maybe this isn't a couple years decision but a life long quest for understanding? Would that be so wrong?
