Yes, Conservative Judaism is a distinct movement from Reform and Orthodox Judaism, generally regarded as existing in between the two in terms of theology and practice.
I don’t quite understand the second question: Most Orthodox Jews never see through the lies, so they don’t have that formative experience. But for those who do leave their faith, it tends to be an important part of their identity.
(Note that I don’t really know what percentage of Conservative and Reform Jews believe in God. I do think that the two movements have converged in beliefs and practices to a considerable degree over the last 50 years. Also, this is a very late response: I don’t comment here often.)
Typo, fixed. I believe I got his age right.
