I don't think everyone is trying to be polite, I've developed a distinct impression that you're trying to be hurtful. Which, I might add, appears to be a response to running out of substantive points.

You'll notice my response to the thread going long was more arguments. It keeps the discussion more respectful when people only push on when they have arguments to make. Not the only option, but insinuation specifically is a weak long term strategy. As are insults, for that matter.
