I believe the word you’re searching for is “schism”.
***Nope. It doesn’t fit.
You are proposing using the Religion forum to sort, label, and catalog the schismatics, according to your religious beliefs, and to sequester them there and get them out of the public square.
***Nope. You need to read the thread before you post this kind of stuff. This is an ecumenical thread, where such antagonism and loaded definitions are frowned upon. I stated my goal right up front, and that is what I’m proposing, regardless of any straw argumentation and mindreading you may wish to employ. What would be your goal, with such an antagonistic tone?
Can you explain why not? It appears to be entirely consistent with the criteria you're using for "whateverism".
I believe you've stated your goal is to reduce the vitriol that frequently becomes an issue on "crevo" threads. Would you entertain suggestions about what you might be able to do to help accomplish that without moving the treads to the Religion forum, labeled as "Scientism"?
