Everybody has germs to spread. And it’s not about fear. At this point it’s about not being an ass. Costco says mask. So you’ve got 2 adult choices: mask, or don’t go to costco. Making any other decision is childish.
Of course it is about fear. It’s about the fear of being harassed by some Karen. For businesses it is fear of sanction by local or state governments. And for others it’s about irrational fear of an overblown hoax.
