Anyone with two brain cells knows that is not about public health. Most of the masks people wear are not high medical grade masks and are useless against preventing the spread of highly contagious respiratory diseases. You would need a full hazmat suit if you were actually serious about not catching anything highly contagious and not giving your germs to others. The only people I see who want everyone wearing a face mask are authoritarian leftists. This is their idea. Mandatory face masks come as leftists protest, riot, loot and burn shit to the ground and face masks make it easy to hide their identities as they do illegal shit but this mandatory mask thing is all for public health and I am the tooth fairy!
