It is very JW of you to think you know why each of us left. They tend to think it's either someone "stumbled us" or because of sin.
I didn't leave for either of those reasons nor do I whine about anything. I don't go to church either, because it's all a crock of shit. Different churches, including Jehovah's witnesses all think they have the one and only true religion and the only pathway to God is to live my life the way they say. Your opinion matters as much as anyone else's - it doesn't.
