Its not black and white - we're not going for 100% security. Masks never did that anyway, and it wasn't the point in wearing them. The point was to change 'R0' to less than 1, so the epidemic wouldn't grow geometrically and swamp the healthcare system. It's quite reasonable to say that vaccinated people are less likely to spread the disease than say, an at-risk person wearing a mask. If those two are commensurate, then sure vaccinated people can go maskless. There are social reasons to keep wearing a mask of course. To reduce confusion about who's safe and who's just being negligent. I still wear one in public, and I've been vaccinated. It's popular to back-seat drive during difficult times, and point out gleefully when somebody isn't 100% in line with one's own understanding. It's largely not constructive, and causes more upset and confusion. The best advice is, do your part to reduce infection risk. And stop stirring the pot.
