Dang, see my supporting response below (1). I'm concerned about the depth of your thinking here. I wonder where "polemical rant" would fall in PG's list of labels used to suppress ideas (2). Just because someone's thesis is not in alignment with anyone else's doesn't make it a polemical rant. Especially when it's actually quite in alignment with the evidence, just presented differently (abundant evidence supports my thesis (3-5)).

Indeed, learning how to express one's sense of truth even if you don't have the entirety of the thing thought out is a central part of entrepreneurship, leadership, and just being decent. I submit it is with utmost humility that I expressed the zeroth iteration and appreciated encountering resistance: it is excellent for sharpening the thought. I know what I think. I need people to challenge me so I can clarify my position. I come here specifically for the follow-on question from someone who is not me.
