I couldn't agree more with your statements Tom. I also agree with Skans, any anti gun person could make themselves look like a hunter, and say that they have a long hunting background. He could be a real hunter, but it's just so easy to borrow someone's shotgun and dress up like a hunter to appeal to people. OR, it is definitely possible that the picture is not even of the author.
They did exactly that in an Obama for pres commercial. They guy is on the tailgate of a pickup, wearing flannel, holding a shotgun, talking about being a hunter and part of Sportsmen for Obama or some crap. My first tip off was he had his finger on the trigger the whole time. Seems to be the first detail antis always fail. Anyways, turns out he was some unknown liberal anti-gun actor hired for the commercial.
