And there are plenty of people who were absolutely fanatical about mask-wearing who still caught it, and others who've never once worn a mask but never contracted COVID. We all have anecdotal evidence but if you look at the spread of omicron, mask wearing didn't slow it down one bit.
If it makes someone feel better to wear a mask, nobody's stopping them. But once the virus entered into omicron levels of transmissibility, cloth and plain surgical masks became superfluous. But everyone got anchored to the idea that masks work and we're loathe to acknowledge the fact that they dont because it feels like giving ground to the anti-vax, covid-deniers.
