I’ve yet to see a convincing argument that my wearing a mask protects others. I can understand that my wearing a mask might protect you if I were infected and you were not wearing a mask. Why wouldn’t you wearing a mask provide you as much protection as my wearing a mask.
Quite frankly, it sounds like ‘made up science’ to justify everyone wearing a mask.
