you said that their love reflects the God they worship....obey me or die. I think a lot of the principles that the bible says are a protection, and obedience is a protection, just as a child obey their parents who are wiser, so to is Gods words, so obedience to Jehovah is a protection. However the shunning is wrong, unless the person is a threat physically or a trouble maker for the family I find that shunning is unloving.
