It is astonishing the degree to which some fight, tooth and nail, against the simple wearing of a mask. You would think they are being required to sacrifice a body part. Unlike in mathematics, nothing can be proved in medical science. There are only weak or strong indications. There is now substantial data showing that masking can slow the spread of covid. The better the mask, the better the effect. Why the fight? It's not reasonable, it is political--though for life of me I can't understand even the political motivation. The necessity and value of using a protective method varies with the degree of danger we face and the protection it can offer versus the damage that method can cause. If one was told that removal of their left thumb might help slow the spread of the common cold, it would be stupid to agree to thumb removal. However, if told that a harmless mask might help slow the spread of a virus that has killed hundreds of thousands in our country and devastated our hospitals, it would be foolish not to wear one."
