The Gov of Colorado just announced they're getting rid of mask mandates. Their rationale is that it won't affect hospitalization rates. In other words, the anti-vaxxers aren't wearing the masks they're supposed to, anyway. And the ones who believe in science will continue wearing masks regardless of what the state says. If getting rid of the mandate will have no effect, all that means is we don't have a pool of "undecided" any more. Everyone has picked a side in this.
Interestingly the mandate is still in force for schools and daycare centers. For health reasons. Because there's a hope of changing behavior in that setting.
