Did you follow the blue links in the articles to the studies?
My only point was in reference to the infectiousness of the asymptomatic, not to masking in general.
They want everyone to mask because (a) there are assumptions they have made about the asymptomatic, and (b) they assume (guilt by association) that most anyone could be asymptomatic, while (c) the same sorts of people say so few people have actually been infected when even some antibody tests find maybe only 10% show contact with the virus. So in the former everyone is dangerous, and then in the latter MOST people actually are not.
But it is all not about what’s true and sure. It’s about social training to be rule followers first and thinkers not at all.
I have no problem with the idea of the masks in general. My problem with the U.S. governors, unlike Sweden, is the governors place universal rules on the table with no room to put any requirement in context, or to understand certain contexts might be very important and some contexts not important at all. Realizing that and using your brain is not what they want folks to do. It’s sheeple not people they want.
