Reason 1: Though some virus particles are aerosolised, most travel on water droplets. The masks catch the water droplets. And even if they didn't, transmission is via nose and mouth, and when a mask is covering your nose and mouth, you're not likely to touch them with contaminated hands.
Reason 2: The more of the virus that's in your system, the harder it is to fight off and the more seriously you'l get ill. If I get coronavirus despite wearing a mask, I won't get as sick as I would have done without the mask, unless I do something stupid like ride the subway then stick my unwashed fingers up my nose.
Evidence 3: Southeast Asian countries where people wore masks before coronavirus have generally had fewer fatalities.
Evidence 4: I work (masked) with over 100 adolescents all wearing masks in a school where social distancing is impossible, and I ride public transport to work every day in the city centre at rush hour, in the biggest city in the country, after the capital. I haven't had coronavirus, the vast majority of my masked colleagues haven't, and the school hasn't been forced to close this academic year. And yet, this country has been quite badly hit on the whole.
to want to punch people who complain when others arent wearing a mask?
