That poll is up for interpretation... one's idea of being active in their church may be different from anothers of the same religion. I don't consider myself active, but I do consider myself religious.
I don't go to chuch often but I believe in god, I don't believe in god as a creator, I'm all for evolution. In my head god is an observer, not an actor. I mean, there is so much up for interpretation this poll is going to be way out of whack.
If you are asking, have you been baptized, that's different, or if you asked... are you atheist? that would be different as well, either you believe in god or not. Religious is too broad of a term, you may want to start a new thread with a new poll.
