A Cloth Mask Does Nothing

It's to make people feel secure psychologically. It's a feel good measure.

Exactly

Oh, is that why local governments are threatening people who don't wear a mask in public with being fined, arrested and jailed?

Yes,They honestly believe forcing people to wear masks (even though they won't help) under penalty of law, will make more people "feel better" than it will harm. It is tyrannical, oppressive, and foolish. I never said that it was right. This is why I am against a nanny government. They think we don't know what's best for ourselves (and in many cases we don't), but they don't either. If I'm going to have someone's decisions mess up my life, I'd rather MY decision's mess it up, rather than the decisions of the nanny government.

It makes a token difference if the mask *wearer* coughs or sneezes.

But even then not much.

No it doesn't do anything. Cloth mask are useless
