They are a form of submission. I get they work in some cases but in regards to Covid they don't do anything. A virus is much smaller than bacteria or germs so it'll pass right thought the paper or cloth. Cloth face mask are especially dangerous because they need to be washed a certain way to ensure that they are thoroughly clean but most peoples washers are made for that sort of cleaning. I dated a girl who had a collection of all the face mask she wore in her car and it was the nastiest thing I ever seen. Just thinking about them and the colony of bacteria growing on all of them ended the date really quickly. No kiss, no hug, no response .
