"The basic science" says that masking protects other people if I am infected with a comparatively high viral load and I am prone to sneezing or coughing unprotected. The basic science tells me to stay home when that happens because I am not fit for public appearances. Normal people stay home when they're sick, they don't infect others, and the basic science takes care of that just fine. If crazy people want to follow "basic science" and mask up and go out in public while they're carrying an infectious viral load, then I guess we're in Japan or something. If "basic science" compels the general populace to mask up, even when we're uninfected, unexposed, vaccinated, and asymptomatic, then I feel sorry for basic science because it's jumped the shark.
