Actually, for those of us who care about facts and real science, facemasks aren't proven and best at all. When you actually bother to read the studies, what you find barely qualifies as science. The studies are poorly designed, the statistical significance is zero, and many are merely anecdote dressed up in scientific clothing. This is Pons & Fleischmann science, e.g. spurious. Which is a great shame. The debate about facemasks and all the rest of it ought to be based on hard facts, not empty assertions or political posturing. As it is, apparently few if any people bother to look at the underlying data. If they did, they'd discover they've been utterly misled both by Trumpies and by the mass media.
