So all they have is what they call "preliminary evidence" and they bring lousy evidence that you can't get it if you're wearing it, aren't we past that? Aren't the great leaders of you saying they prevent you from spreading it?
There is a ton of hard evidence that mask wearing prevents transmission of COVID-19 to others. There is also a lot of evidence that mask wearing protects the wearer from COVID-19, and there are decades of research proving that masks protect the wearer from most transmittable diseases.
Do you really want to see proof, or are you fighting masks because you don’t like them? The proof is everywhere. Find me a doctor or scientist who disagrees. Perhaps your personal doctor disagrees? Because I have yet to hear it from any doctor.
