No idea. All I know is the OP image, and the general rhetoric on both sides tends toward the idiotic. A mask is not 100% effective. It's also not 0% effective. On a macro-scale in public areas, it seems obvious to me that mask wearing would reduce the amount of virus in that environment. Masks stop large drops of spittle from landing on surfaces, and protect your mouth and nose from the same. Handy if in a crowd. Personally, I don't wear a mask (mostly), but I live in a sane State that avoids the impulse to micromanage it's citizens.

I can respect that stance.
