suppose putting a mask on every asymptomatic wasnt going to make a difference; suppose they always knew that?

why would they say the opposite?

the logic on masks is easy. i wasnt asking about that

C'mon man.

Docs and nurses wear masks, too.

Why would they if they were useless in germ spread?

Because nobody really knew or knows all about the virus even now.   So  If there’s a chance a mask prevents the wearer from catching it or worse spreading it to others, then it’s worth wearing.  
There’s no proof that taking vitamin supplements is going to make a difference in someone’s health, but many still do it.

But masks do make a difference.
