I find it very sad that a parent can say to a son/ daughter who is disfellowshipped:-
" look how much we sacrificed for you, when you were young, now you have forced us to shun you"
In my opinion a parent should always say :-
" You did what you feel right. We do and will always love you. We can not shun you"
However if a son/daughter is shunned by parents, they may find it hard to honestly say to a parent " You have done what you feel right, shun me, but I will always love you"
So too clarify my O.P. I am trying:-
A) To understand the factors that make people believe things.
B) To understand how a belief system can influence people to do things I think immoral.
And most importantly, self examination:-
C) In what circumstances am i still capable of living with " false" knowledge that will cloud my " moral attitude?
And my conclusion is we are all challenged in life. We will all believe " false" knowledge and we all do things " immoral" even to our own standards.
