When I prepared for my baptism there were few questions on disfellowshipping and none on apostacy. There were no questions on the need to cut off family members or the possibility that I may have a change in viewpoint. None of us were told about the dangers of changing our mind when we made our commitment, nor were we asked to reaffirm our baptism each time they changed the doctrines or the questions.
To my point of view the organisation I thought I joined was not the same organistion I left behind and they have no justification to cut me off from friends and family.
