The science is not, as you say, “clear cut”.
The Corona Virus measures 0.1 micron.
Holes in a typical cloth mask are 20 to 30 microns.
It’s like throwing a fistful of sand at a chain link fence.
Even the vaunted Dr. Fauci and our august Surgeon General have flip-flopped and flop-flipped on masks.
N-95 and above are effective but it’s impossible to manufacture them on that scale. This is all a head fake.
Corona travels via water vapor that is considerably larger. It's more like throwing ping-pong balls at a chain link fence.
“This is all a head fake.”

I know....that’s why it is so frustrating to me. You would think in the times we live in, people wouldn’t allow themselves to be fooled.
I see people going into stores with bandanas or even pulling up their t shirts to cover their mouths. Home made fashion masks aren’t doing ANYTHING.
Why are we doing this?
A nation of sheep.
