I think much of this is quite unreasonable (and some very unreasonable- you “don’t like that I spoke as spoke as an authority on her life” because I wondered if what she observed was truly attributable to a causal effect?!), but I don’t see the value in going over it, especially as others have made the points I would make about your tone and framing elsewhere. I continue to find your contributions on this topic a little more combative and “soldier mindset” than is ideal, but clearly you strongly disagree. (Although it’s tempting to suggest that your admittedly “angry” and “unfair” reply, several times longer than your eventual response to the object level question, is evidence for the prosecution, not to mention that it somewhat calls into question your primary ‘it’s too much work’ defence for ignoring substantive criticisms such as Chen’s in the first place.) I don’t see the point in continuing to argue about whose team is more rational, in any case; all I wanted was your response to Chen’s objections to help inform my new dietary choices (something which, again, you concluded was worth dozens of hours and tens of thousands of dollars when multiplied by six, a matter of months ago).
With all that in mind, I have a few follow-up questions to your object-level response, but I will understand if you choose to ignore them, given that you don’t seem to enjoy or value the interaction and I’m finding it lower value than I’d hoped, myself.
By what mechanism could natural selection have optimised our diets? Why should we expect long-tenured features of our diet to be necessarily healthy? We have consumed alcohol since long before we were modern humans, as one obvious counter-example to this sort of argument.
