The only thing worse than being a doormat is being a foolish doormat.
You are assuming anyone will care what you have to say, they wont. You will be branded an apostate and you will lose your family. You are making this whole thing about yourself and proving some vague point.
Your plans and your desired outcome don't match up.
You need to realize the whole thing is just a game. You need to play by the rules if you want to win and acknowledge you're not in a position to win right now. You need to backup and come up with a better strategy.
If your ultimate goal is to keep your family, play along with your wife's current needs. If you want her to follow you out, you must first be able to lead. You need to earn her respect, then make a move to leave the org years from now.
Personally, I don't want you to lose your family or your stepson to lose another dad. So, with kindness in my heart, I tell you to stop being a dumbass!
Play along and be a great dad, respected husband, and a casual JW.
