"Witnesses definately aren't perfect"
I hear this sort of thing from individual JWs a lot, as in "Well, they're the best of a bad lot". Understand that this is not the official position of the organization, though. The current party line is that the Jehovah's Witnesses have the "truth". God is using the organization to dispense "truth", even when it isn't true.
Returning to the JWs involves more than just going back to the Kingdom Hall and making friends. It involves going door-to-door spreading "truth". How do you feel about telling "wordly" people that Jerusalem was destroyed in 607 B.C., when it was not? How do you feel about telling "worldly" people that blood transfusions are forbidden by the bible, when they are not?
Is it worth spreading lies in order to make friends?
