I know of the guy you are talking about. He just seemed to disagree with people just to get a reaction or play devil's advocate. I never knew where he stood on anything becuase alot of his answers seemed too take both sides of any argument.
I don't mind if he came back. I just hoped he would be more consistent in his answers. I know most of the regulars here, and they are consistent in their views. I don't agree with all of them, but I least I know what to expect.
