You might want to discuss the 3 to 5 year rule for elders who commit serious sins, keep their mouths shut, and then come forward but don't have to sit in front of a Kangaroo Court. Make sure you emphasize how vital these "gifts in men" are to the Org, and that Jehovah blesses this fine "arrangement" for one-time philandering elders to not have to go through the same humiliating procedure that the unwashed, less-important R&F do.
....And then you could say:
" My Bible-trained conscience will not permit me to pretend that this kind of hypocrisy and double-standard is acceptable to God. It doesn't align with my sense of justice, so I cannot believe it aligns with God's justice."This has been the way the organization has been for a long time, and its' not going to change, no matter how long we wait on Jehovah.
"I'm tired of waiting. I am announcing my disassociation from Jehovah's Witnesses effective 10 seconds from now."
... Then you could head straight for the door.
