What about covid makes you think masks are ineffective when they've been broadly considered effective in the past, and in places where germ theory didn't become a political issue?
The screens on my windows don't keep out each and every creeping crawling thing, but it keeps out most. I wouldn't call it trivial either.
- dragontamer 5y ago"Miasma theory" led to mask usage, even during the bubonic plague. The technique of masking up is nearly 1000+ years old (and maybe there are older historical examples that I'm unaware of...) The only time "Miasma Theory / Masks" didn't work out was Cholera in the 1800s, because that was from drinking-water instead of an airborne disease (which eventually led to the discovery of microorganisms and modern theories of disease). But there's no denying that COVID19 is airborne. (Sure, we had worries about physical contact in March/April 2020, but today in 2021 we know its airborne). Otherwise, even the primitive middle-age peasant knew masks / miasma theory was effective to prevent the plague from spreading.
