Comments are moderated. My moderation follows the same heuristic I recommend to friends attending debates at my house, “Imagine someone will actually believe the thing you say. Say the most important thing you’ve got on this topic.”
That means comments may be deleted for (a) not being on the topic at all, (b) picking a picayune fight rather than presenting a positive case for your alternative, (c) being a RenFaire like reenactment of a fight you have previously had in the comments with me or another commenter—if it didn’t work out last time, try at least to have it fail in a new way.
I’ll allow things that aren’t responsive to what I posted if I enjoy your comment.
