Earlier quoted context omitted.
Look, I repeated told him that the units didn't matter, and that it was the ratio that mattered. Other than disengaging sooner (which I would've done if I'd any cop-on myself), what could I have said differently? I'm truly at a loss. I straight-up wrote this: > _The units are irrelevant._ That's what you're not getting. What is relevant is that the same page width/height ratio is maintained between the different page…
You shouldn't have said "You appear not to understand the actual utility behind the page width/height ratio used in ISO/DIN page sizes." Turing_Machine wasn't talking about utility at that point. Ve had misunderstood something confusing that you had said, and you basically straight up said "you're dumb".
> The 1:sqrt(2) ratio used is extremely convenient as it scales up and down nicely
Then he wrote this:
> How are factors of 2 and sqrt(2) "based on metric"? At some level you could say that the U.S. measurements are "based on metric" since almost all of them are defined in terms of metric units. You just have to apply the proper factor (which is a decimal, but a terminating one --- unlike the sqrt(2) business).
(Emphasis mine.)
That is where the "You appear not to understand the actual utility behind the page width/height ratio used in ISO/DIN page sizes." comment came from. I wasn't calling him dumb. I hadn't flipped the bozo bit on him at that point, though I had by the time I wrote "Ok. I'll be super explicit about this." later on.
