Mask wearing is important, and I wear one regularly as required, but mask shaming has got to stop. There are plenty of legitimate medical reasons for people not to wear one. I have a friend with two autistic children, for example (one older), and taking them out in public is already challenging -- (not to mention her children are still trying to adapt to a masked society), without worrying about comments or dirty looks in public. If you see someone without a mask on and you're not responsible for that business or venue, mind your business, keep your distance if it makes you feel better, and move along with your day.
