Germ Theory says that viruses are present in our bodily fluids like snot if we are infected. And that when we cough or sneeze, these droplets can fly out and land in someone else's mouth or nose or surface to be picked up later. Me: So Mr. Virologist, let's check the snot for viruses. Virologist: Oh, we can't. We cannot find viruses that way. Me: Well can't you find bacteria and bacteriphages that way. Virologist: Look. I can't have a conversation with someone who does not know how we've been doing virology for 100 years. You just can't understand how it works.
