Excellent article. It's well thought out.
I'm amazed that your father wants you to just let it go. That is the type of person he wants you to be?
You are following the narrow and difficult path that the bible talks about. It will be hard, but in this process I do believe that if you continue presenting yourself in a calm,
and logical manner, then maybe, just maybe you will spark something inside an elder or two that has read your letter and discussed this issue with you.
You may lose a lot in this process, but you will sleep well at night knowing you did the right thing and knowing that you may have helped someone else see the light.
