Expecting small children to think/feel/act/talk all Jehovahery at the KH and in ministry and around other witnesses and then do things the parent's way at home is NOT the answer. In my opinion that would only succeed in producing very mixed up, confused, damaged adults.
The the only reponsible action to take against WT propoganda and indorctrination is to not expose your child to it.
In other words stop taking them to meetings.
No sane person would expose their child to white supremacist meetings and excuse it by telling the child in private
"That's not how we do things in this family son, regardless of the meetings we attend"
That's just madness!!
