Arguing back and forth about the science isn't really going to solve the COVID problem. Almost nothing in this world is clear cut, perhaps initial data showed one things, then more studies showed something else. I have no idea - I'm not a doctor, I fly airplanes. I just want people to feel comfortable flying on airplanes so every airline out there doesn't furlough 3/4 of the employees.
If that requires people wearing masks when engaging with other people, then so be it.
