When i started to move away from OJ, it was because I just didn't like it. It didn't speak to me at all and I did not get any spiritual uplifted from it. The minutia of halacha was incredibly annoying to me. And, unlike JP would like everyone to believe, it had NOTHING to do with wanting sex, drugs, or the like.
After a while like this, my wife encouraged me to seek out answers to my questions and to deal with my feelings instead of just giving up on it. I told her that I would honestly look for answers, but that she has to also understand that the conclusions I reach may not be the ones she desires. So I started to pay attention to the torah reading and actually read through it on Shabbat afternoon. I also began reading books that dealt with questions on Judaism or science/torah issues. I critically read some of the skeptic blogs and tried to look at the issues from a fair vantage point. Similarly, I read blogs from a traditional OJ vantage point.
Yet, what happens in the end of the day when the answers just don't satisfy one's need? Does that give one "permission" to leave the fold and follow the answers they have found? certainly not according to traditional OJ. Seems to me that people like me are really left in a bind because of this.
On one hand Judaism likes to state that, unlike Christianity, we are allowed to ask questions and think critically about our religion. On the other hand, if you are only allowed to come up with answers that lead you back to "proper" OJ, then you really aren't allowed to question after all.
