I have learned the hard way;
You do not have to be a Jehovah Witness to be infected by the disease mentality.
You do not have to believe any of the doctrine not one line of it.
You can be challenged by their best propagandists and win every discussion or argument and still be infected. In fact in my case that was exactly what happened and exactly what they settled for.
Judging others and arguing or debating becomes addictive when you have to win. You have to be right. It's nothing less than foolish pride. It makes you impossible to be a friend; No one likes to be put down.
What I am trying to say is that maybe it is not just "what" the Jehovah Witnesses believe instead it is "how" they choose to believe and what they do when they present it.
Controling others is loosing game.
