May be easier to just ask admins for a caucus.
I interpret Swordmaker's admonitions as requests for common courtesy and mutual respect. They're not rules, the way a caucus would have.
A caucus says (sort of): "If you can't say something nice, don't say anything at all." Disagree, yes; argue, no. (That's how I interpret the rules, YMMV.)
The tech threads are still a good place to have an argument, if it's on-topic and not personal. To quote Monty Python:
"An argument is a connected series of statements intended to establish a proposition."Whereas a verbal food fight is something else entirely.
No need for a caucus, since a good argument can be fun and enlightening, as long as we all manage to conduct ourselves as civilized adults.
