Correct. He is a simpleton. 'Hole is smaller than virus, therefore mask does not work'. And then he wants you to speak with authority about why he's wrong. The virus can't escape a mask because the airplane it needs to transport it IS bigger than the hole. Maybe that will sink in. Maybe not. Who cares at the end of the day. I cannot teach advanced calculus to my Cairn Terrier. It is what it is.
Yeah, some things are self evident. A basic knowledge of the transport of the virus tells a reasonably intelligent person why masks work. The problem here is that Evmetro, among others, does not fit that description.
My favorite lack of protection are the morons wearing this paper masks that have no seal anywhere.
