While I wouldn't recommend it for everyone, I openly threatened the two elders that "invited" me to a JC. I was calm and quiet, but painfully direct.
I realized if I didn't stand up to these guys mentally, emotionally, and physically, they would haunt me forever. I would always be hiding and pretending because some random guys imagined they were my superiors and demanding I be submissive to them.
I told them "no" and they accepted it because I gave them no other choice. I am still friendly with them and chat whenever I see them. I am not angry at them anymore, they are just ordinary guys now, not elders.
They seem to realize I don't fit in their group and I dont need shepherded like a helpless sheep. If you act like a sheep, someone will always attempt to shepherd you.
