The JWs serve a false god who is bloodthirsty, harsh and demanding, with no humility, subjecting his people to mental abuse, denying them happiness, and teaching them to hate others. I would rather my kids serve no god at all.
The JW idea of faith is to never receive real help from their god, to never be sure if you will make it to their false hope of the new world that will still separate the "right" people (heaven and earth) and destroy all of the others. You prove your faith by subjecting yourself to more and more abuse and giving up more and more of yourself.
The God that I have come to know doesn't just sit back and watch you stumble and claw your way towards him and punish you if you don't make it far enough or quickly enough. As for faith, my God is with me to help me every day and has assured me of my salvation.
Flawed faith? No thanks.
