This is hilarious because it's so true... There's also a conversational/argumentative style where you take the opposite position, either because you like to go against the flow or because you want to see how well the other guy's argument stands up to yours. I think if you look at my comments I tend to have a lot that are "well, no, <contrary idea because reasons>". If I'm at all representative of HN, it would surprise me if part of the HN Cycle™ is contrarianness.
