isaac I don't have a problem with ex-Jws helping ex-Jws it's the actively trying to recruit more and working against the congregation I do not admire. Early Christians didn't try and change destroy the churches around them they only preached God's message as Jws do.
Iaac does the bible support leadership of men until Jesus's return?
Therefore any church is right to have leaders.
Your issue then must be with the teachings/doctrines that do not equate with what you believe therefore it's not the leadership at all.
You would not have a propblem with the leaders if they taught what you believe in?
