I wasn't really sidestepping, I was just dancing my own jig a bit in the direction of an answer. I think I lost my train of thought, and just ended.

For your question, I think most of my jig was relevant. If we're talking about political power, given the tribal nature of the competition, and the realities of democracy, and population IQ variation within populations, and the political culture of significant dishonesty, then it seems to me that most any political cause requires the Dark Side, so needing the Dark Side is not particularly predictive of a bad argument.

The need of the Dark Side does not come from the particulars of the argument, but from the context in which the associated political power is decided.
