How do *I* feel about wearing a mask in enclosed spaces? It beats the HECK out of being DEAD.
But if someone doesn't want to wear a mask in an enclosed space... they can feel free to go to an enclosed space where I'm not located... and just run around with or without a mask to their little heart's content!
For MY money, here's the who, why, and how:
WHO: People who don't want to infect others wear masks. People who don't give a rat's ankle about others don't wear them. It has nothing to do with "freedom" or patriotism.
WHY: See above.
HOW: Put mask up to cover nose and mouth. Place bands around ears or head, depending on mask's construction. THEN stay at least six feet away from others.
Lather, rinse, repeat.
