However, they are welcome to start a new, similiar "open" thread or to repost the same article at least four hours later as an "open" thread.
“They may be interested in discussing it,...”
They may be more than interested in discussing it. In this case, were the LDS folks to strongly disparage the doctrine of the Trinity, and we Catholics gave an inadequate defense thereof, it seems unfair to me that other Trinitarians would be forbidden from entering the “caucus” thread.
But I see why you want to provide that option.
It is difficult for theological arguments to deepen when they are subject to the inanities of haters.
The parallel thread concept reduces a little the inherent injustice of the arrangement that you've created, while preserving the good that it does do.
Thanks for the clarifications.
