They didn't seem too scared of it when it was still new, and when next to nothing was known about it. How dangerous is it? They could have been spreading a disease as serious as the Plague, for all we knew about it back then--yet they were still doing field circus door to door.
Now, we know that it barely causes any sickness at all--and that being exposed to it while taking simple quercetin will render the "disease" so wimpy that you would get sicker simply breathing the dry cleaning fumes from people's suits. And yet they still expect people to wear those useless masks, after we know they do not work and that the "disease" is the wimpiest on the planet? Not to mention, trying to require vaccines that are the real threat as a condition to returning, on the whim of just one hounder?
