A significant portion of the population still believes masks don’t work because their favorite talking heads told them they don’t.
I made the mistake of going back to Reddit ONCE and got in an argument with an alleged “MPH” (master of public health) who was adamant masks don’t work, despite the overwhelming evidence they do. He ended up threatening to stab me with an icepick. Multiple times across various, unrelated threads. Reddit actually banned him.
These motherfuckers are out there and they’re some combination of stupid and crazy.
