Well, we could make our own caucus rules and post them at the top of caucus threads.
When a Catholic/Orthodox caucus thread is posted and the RM refuses to honor it for any reason, we Catholics can refuse to engage the crashers. We can pretend that they aren’t there.
I can say from my view that I have not seen one of their posts which made a significant and valid point. Their posts might mislead other non-Catholics but they can’t touch my faith.
“... we Catholics can refuse to engage the crashers.”
We can try but I’m even being harrassed by FReepmail now by one of them.
