Before you walk out the door and cause your mother to cut you dead, ask her this simple question - "Mom, are Jehovah's laws and principles so flexible and open to interpretation that we can communicate with each other and have a normal family life if I continue to live here, but if I move into an apartment next door, you will be obligated by the Organization to cut me dead? Can you show me the Scriptural reasoning for this?".
Those who teach this falsehood, and those who apply it, are anti-Christ, whether they know it or not!
I really feel heart sorry for all who are afflicted by this demon-inspired, hate-filled dogma which contradicts Christ's own command - John 13:35.
Best wishes for your life-choices. It won't be easy either way, but choosing the one which gives you a clean conscience and respect in the eyes of those who REALLY matter - that is ultimately the best way!
