And how, exactly, do you conclude that I'm American? Or that I've not worked professionally on three continents?

Cool assumptions, bro.

And why propose a thought experiment if you're just going to dismiss criticism as a reflection of the critic's nationality, instead of evaluating them on their own merits?

You didn't address a single counterpoint I made; it sounds like you're not interested in a "thought experiment" so much as proposing your idea and then not hearing any criticism.
