There was nothing shallow or curmudgeonly about my response. I was careful in explaining why giving examples like this is missing the point and why the examples are not what I'm talking about. I excused myself from attempting a point-by-point rebuttal because I know from past experience that this only leads the discussion deeper into the mire with no insight.

I have been trying my hardest to explain reasoning rather than simply accumulating evidence. But the entire discussion has been wildly off-topic from the beginning, so I don't see a reason to continue anyway.
