Surgical masks have worked for over 100 years since ciourgeons teeth pullers and embalmers admitted to "germ theory" but only to protect others from the wearer

It's amazing how things that have been accepted fact for generations can suddenly become opinions. How long have surgeons and dentists been wearing masks as an unquestioned safe and effecting way of reducing the likelihood of them passing on germs to others in a vulnerable position? Then suddenly when certain truth twisters are asked to do the same it becomes an opinion that maybe they don't work, maybe they're even harmful. I'm not sure if the people spouting this nonsense believe it, or even have an opinion of whether it's true. Surely no-one can be that dumb, surely it's the meaningless mantra of the sort of selfish egoist who hates being asked to do anything for someone else's benefit.

Next time anyone comes near me with a lit propane torch and a spray can of fire starter, I will DEFINITELY wear a mask.

Looks good for masks

Apart from math, science doesn't PROVE anything. There is always doubt/error-bars/new-ideas. It can disprove things. Some folks likely will never be persuaded, no matter how much convincing evidence is shown.
