He is preparing to put up more crap because people keep responding to his posts and he gets off on that. It would be better if people just ignore his posts. He is just a classic attention seeker - every time someone shows he is wrong about something, he just starts something else. And he will continue to do so. He switches between arguing one way and then another - anything to take a contrary viewpoint to keep the ball rolling.
Step back and take a look - he dominates all the threads in General Chat. I wonder why people don't join this forum any more. I know there are facebook and other forums but I think there would me more productive discussions on here if he disappeared.
