Like, "if you won't trust the voting public enough to give them the whole truth and instead treat them like blubbering fools, how can you--with a straight face--pretend that their ability to pick leaders or vote on actual issues is a correct way to run a country?"
So instead of compliance, they'll bring the whole damn thing down in protest. I don't think the plurality of those who refuse the vaccine actively deny the existence of the virus, or even the efficacy and safety of the vaccine. I feel they're just absolutely sick of the hypocrisy and pandering by "leaders" who refuse to lead by example on much of anything.
As many before me have said, you'll always have the kooks that deny science but I honest-to-God think those are the minority.
