Have any of you had this experience where you have allowed your JW families to continue to see your children?
First, my condolences for your loss.
They are playing victims. They are full of shit, not necessarily by their own merit, but mostly because that's how they feel loyal to the WT, that is, because of their brainwashing.
The number one tactic that cults, controlling groups and conservatives use on a daily basis is to always trying to portray themselves as victims in every situation. That way they gain allies, they get others to see you as a bad person, and they reinforce the nonsense that they believe.
I'm so sorry that you are going through that. It's unwarranted and hurtful.
