Hi,
I am so pissed off and full of rage, please advise me!
You have good cause to be angry. Yet anger will not help you to get the outcome you want.
Consider carefully: first where you want this to go. Do you want to fade or to go out with a bang? JC or no JC? What you say (and hopefully record will give you some satisfaction, but from all I've read, the elders will simply label it all "satanic" and stay with their chosen beliefs.
If you do go the JC way, prepare 2 or 3 main points and research them very carefully. If possible get someone to practice role-playing. The hardest will be to keep the elders from shouting you down, changing the subject, vilifying your sources, anything but addressing the points logically. It is so very difficult to maintain a polite and logical position against numbers and men who think they have authority.
I wish you all the best.
