Well the point of my strategy was to try to avoid those "tricky" little ways they will have of indoctrinating the kids. Is there something my above described strategy does not cover.
One particular problem I see is that you mentioned that your wife believes what the jws teach....in that case, she believes that those who do not follow the ways of the jws will be destroyed in armageddon ... wouldn't that mean you?
I think that any person who truly believes this teaching would fight like heck to keep their family from dying in armageddon.
I do think you're in a position of power being that you are the "head of the household" but that does not give you authority over what your wife is taught by the jws or what she feels or believes to be true.
Just my two cents, I guess.
