In times past, they've had some schism problems in Africa - not paying taxes, local
spiritism, etc. I once asked a third world Gilead missionary about causes for disfellowshipping
with the thought that things must be more radical in poor countries. He seemed to agree
and told me about two cases recent to his experience involving a machete murder
and bestiality. That's more than your usual fornicatin' Witness kid.
Oh by the way, the Watchtower has had strict rules about polygamy - you gotta
live with the first wife, period. If you want to dodge this, pick the one you want
before you become a witness and live only with her, as you "come into the truth".
