Unfortunately, my understanding based on reported surveys [1] is that if the non-voters had voted, Trump's margin of victory would have been even greater. If that's the case, then those who say that my 1/3 figure is too low are correct.

Put another way, if someone asked you to estimate what the split between the one third of the population that didn't vote was, what would you use as a reference point? Social media posts? Vibes? Or maybe polls leading up to the vote that showed the same roughly 50-50 split found in the actual results?
So I don't think we can extrapolate confidently at all. So we really don't know whether it holds for the rest of the population at all.
But the parent was — the implication being that if the other third had voted, surely they would have voted in greater proportion for Democrats than Republicans. That’s based on nothing but vibes and assumptions. I argue that the 64% share of people that actually did vote give you a lot more confidence in how the remaining third probably would have voted than whatever the parent suggested. It’s at least a starting point for extrapolation.
