There is no data on anything. Nobody knows if herd immunity is actually a thing, since we have these pernicious reports of reactivation or reinfection. Nobody knows all the side effects, neural, cardiovascular, or other. etc etc etc.
So, in the meantime, why don't we all try not to be dicks, and recognize that people are very worried about this thing, and not get in their faces by not wearing masks? Is there some harm in you strapping a t-shirt on your face to make someone feel better?
