May I ask why you left the Mormon faith and what was the reaction?
IIRC our moderator Thomas was a former Mormon and I'm trying to think who else. Hopefully he can chime in.
For me, the LDS faith has many problematic issues that, individually, were not so difficult to handle. However, altogether I felt I had no choice but to admit to myself that I could no longer believe in the faith's doctrine.
At first I would say to myself "but I know a lot of very intelligent people who are able to remain LDS" so I too tried to find a way to make it work. However, what I found was the arguments people made for remaining LDS were not doctrinally based. Instead they argued things like "the church does a lot of good things", "the church helps me to be a better person", and "there isn't anything better out there." Thus I began looking for a faith that had truth rather than the qualities of a nice non-profit organization.
