There is no "three-to-one" margin. You don't get to claim agnostic/DGAF as votes to affirm your silly fork, which actually only enjoys 60% support against the negative/status quo default presumption.
His math is correct though, if you have 60% X and 20% Y then you have a 3-to-1 ratio
The math is correct, but it's 60% pro and 40% not-pro. So 3:2. Not remotely close to even rough, much less sipa's extremely wide, consensus.
I don't know why you assume that agnostic/DGAF should be on the anti side. If I wanted, I could arrange the numbers this way:
Anti: 20%
Not-anti: 80%
It makes as much sense as 60% vs 40%. That is, no sense at all.
Logic 101, bro.
Presumption is negative. Burden of proof falls on the affirmative.
Why? Because if presumption was affirmative, we'd have to prove negatives to rebut it. And you can't prove a negative. QED.
You should have learned that in high school. Consider suing your teachers for doing a really shitty job of educating you.
