I understand. It's easier to stay in if you still believe most of the doctrine, just thinking maybe that you believe in Christianity & although the society has got a lot wrong they've got a lot right too?
If that's the case & that is what you believe, then it is tolerable to stay in.
I was in that position for a while, but I carried on reading & studying, and eventually the whole edifice came crashing down and I lost my faith. Every meeting now is a test of endurance & I won't be going much longer!
