"Polarik clearly makes the case here. Some of these guys are not following his reasoning very closely."
The problem isn't his logic. His logic is clear and accurate. The problem is that he has proven a jpeg image posted on the Daily Kos is a phony. So what? Most everything out there is phony.
Think of it this way. If I create a bad image of Obama's BC and post it in FR, and the folks at DU or D.Kos proved it to be false, just how does that mischievous behavior transfer to Obama?
