The fact that there is disagreement does not imply there is no truth of the matter. You could claim that I merely disagree with the notion that 1+1=17, but nevertheless I would be justified in insisting that a teacher teaching this "fact" should be fired.

The modern Supreme Court majority contradicts itself from one day to the next. See how they claim it's legal to fire officials of independent agencies like the FTC without cause, but illegal to fire officials of the Federal Reserve without cause, despite the Fed being an independent agency like the FTC. The decision is nonsense, and any organization that makes decisions like this is broken.
