This is a very common thing outside the bubble that is the US. In fact, before COVID it was totally normal to see people wearing masks when they were sick in public places. A little strange to see, but still normal and nobody really cared. People didn’t give two shits back then versus now where they stick out like a sore thumb. Before you’d see someone wearing a mask and think “oh, they might be sick” and move on with your life before you even had a chance to put it into your long term memory. It’s not that it’s weird to wear a mask. It’s that everyone forgot that it used to not be weird at all. The fact that they are getting judged in the first place would seem completely ridiculous 5 years ago.
