Do you have anything to support this “dummies” claim? What I remember from the N95 “guidance” (it wasn’t a “ban” iirc) was that the reason was to ensure there was enough supply of them for healthcare / frontline workers, who need them more than the rest of us, which made sense at the time (and I can see reasons why it would change later). I’m curious when that reason switched to “you are all dummies who can’t be allowed to use masks”?
