But would it not be linguistically simpler (and maybe less taxing for the reader) to use emphasis without resorting to percentages? The fact that 100% can be mapped to an unqualified boolean ("Yes, in favor, no buts.") and 40% cannot be doesn't mean that either are appropriate.

It's not elegant to parse sentence structure as categories to contrive percentage use as correct, even if it's technically sound. I understood the parent's sentence, but I had to read it several times because it just came across as a bit odd.

Honestly, when we start using category theory to analyze whether or not someone has appropriately quantified their stance on something, we've gone pretty far off the reservation.

I suppose my overall point here is that we shouldn't use percentages to quantify our opinions in place of emphasizing in a more linguistically elegant way. Maybe we'll have to agree to disagree?
