Here. I have a talk to get ready for and I won't be able to think much about this before tonight. It isn't clear to me, in general, how much arguing I want to do here. In some ways that's the point, but it gets old and/or nasty quickly.
One rule I have sometimes considered is that a reply has to be less than half the length of whatever it is replying to. Exponential decay being the rapid process that it is, after a few back and forths the disputants can yell,
at each other and that will be the end of it. I think Callie's post is longer than mine, but I hadn't invented the rule yet.
