I'd like to have a post that added something meaningful but all I have to add is frustration with humanity.

What's happening is that our loyalties keep us from widening the frame enough to incorporate all available information. Instead we try to exclude any information that 'helps' the other side and block it when they try to bring it up. Most heated arguments now appear to me to be of this nature. At root, we can't and won't hear each other's stories. In this way the gruntwork of moderation has turned out to be a protracted exercise in forcible frame-widening—something that is painful in its little steps but also has an expanding effect that may (or may not) be worth it.
