You said show respect. And the rest of your post is somewhat infantile. We are talking about spreading a disease. Don’t distract by pretending making a mishaberach is the same as walking into a crowd while carrying a virus. Please.
If you want to mind your own business and ask others to as well, then stick to a situation that isn’t airborbe. Are you also the guy who drills the hole under his seat on the boat and tells everyone to mind their own business then too?
