I literally cite the CDC on masks with exhalation valves, and this is the "mental version of COVID". I get it, I've been lectured to by folks like you repeated

I literally cite the CDC on masks with exhalation valves, and this is the "mental version of COVID". I get it, I've been lectured to by folks like you repeatedly. And this is where public health credibility goes to die. There seems to be a crazy desire of public health folks to preach and be surprior, put down others, even though their advice has been so wrong, and many of them are wrong on the actual science, the risks, the tradeoffs.
