“Masks do not work to stop viruses.
High School biology should have taught you that.”
Viruses don’t have wings. They require transport. That is in the form of saliva or mucous droplets (that are, in fact, generally too large to pass through the holes in masks).
Masks stop some of those droplets. That reduces the quantity of virus in the environment, in turn reducing the amount of exposure by an individual, on average, providing them with a better chance to develop antibodies or engage other immune system defenses in time to avoid serious illness - in other words, be part of that asymptomatic cohort. These are all easily verified facts that you can look up.
Your High School biology class was clearly of low quality.
