Wow! What a stressful time for you.
I tried for a few years just to tell my JW family a few of the points you raised, and only to get the "It's the Truth, the closest thing out there" argument.
Then, I came to a realization. THEY NEED the religion as much as the religion needs them. Each of my JW family members are seriously broken people. They MUST cling to the Truth, because it is ALL they have. For my elderly parent, it would be too cruel to take him away from it. For, it would be a realization that he wasted his life. It gives him a social structure. THe more the JWs have vested in the Truth, the harder they will stay in it.
I suggest you totally lay low with all JWs on JW matters. Go to a meeting here & there to help them realize that you are not against God.
Perhaps if you do discuss anything at all, discuss only injustices with your wife. Pedophilia and spouse abuse should hit a nerve with her. Discuss it with your daughter in mind.
