You're conflating truth with fact. Or maybe I did that though imprecision in my comment. Either way, I'm not talking about a grand concept of individual truth. I'm talking about whether Trump won the popular vote in 2016. I'm talking about whether his inauguration crowd was the largest ever. I'm talking about whether there was any evidence of widespread voter fraud.
We shouldn't be afraid to be decisive about SOME truths just because we can't be decisive about ALL truths.
