Over 300 posts and not a single response of substance.
You are on to something and what few responses that are surfacing are increasingly suggest less that Rog is looking for a discussions as much as he wants to post provactions. If I want that I can read the crap at DU. I give him half an hour to get to the business of 'discussing' some of the respectfully asked questions and failing that delete this thread BUT allow Roger to keep his posting privileges but ensure he uses them in existing threads rather than post his own, at least until he proves himself.
Give the poor guy a break.
This thread was first posted at 9:37am, and your post number 367 at 11:08am, a mere 91 minutes later, makes a response rate of 4.03 posts per minute, or nearly one response every 15 seconds, nearly all of which are directed to him.
If he took five minutes to draft a response to a single post, he'd find himself 20 posts behind by the time he submitted it.
