I think a separate discussion post would be useful. When I wrote this, I was thinking of the PoC as something like an axiom that's not explicitly built into logic, but is necessary for productive discussion because otherwise people would constantly nitpick or strawman each other, there would be no way to stop them, and so on. Based on the discussion here, though, it's seeming more like a tool intended for social situations that's usually suboptimal for truth-finding purposes, although again, it's still better than always going with your initial interpretation or always going with the least logical interpretation.
