Covid is not really airborne in the sense it doesn't float by itself but travels through micro droplets of saliva, which is... (dramatic pause) a bodily fluid!
How on Earth, after a year, you are so ignorant about it?
That was the messaging in the first couple of months, and why social distancing was thought to be sufficient: The droplets would fall to the ground before traveling very far.
Then several months later we started hearing about how the virus can hang in the air for hours in buildings with poor ventilation; that's aerosols, not droplets. At that point social distancing does almost nothing, and even masks are questionable since it can far far more easily go around the edges of any masks, and slip through cloth masks in ways droplets can't.
I am not going to debate my own ignorance, only fact here : you're impolite sir. And you know that most germs are destroyed by oxygen and sunlight ? And the spanish flu backfire was provoked by masks ? And microdroplets fall to the ground they do not levitate in the air ? Do you know about gravity ?
