I probably could have worded that a bit more clearly. I was trying to make the argument that there is an anti-truth faction and that this faction is currently in a much stronger alliance with the right. I'm under no illusions that it's exclusive to the right, though, and was thinking of adding a section on anti-vax to clarify this.
In any case, I wanted to stay away from reflexive both-siderism as I've most often seen it used as a bad faith argument.
