Well, as were comparing his false facts with my false facts, I didn't think it was my job to prove 90%. On the other hand, maybe he can prove no more than 10%. I think nonsence makes the point. If wearing a mask makes me even a little bit safer, and having you wear a mask when near me makes me safer still, then I think I'll opt for the mask. And I'll try to avoid being near those who don't wear masks. Especially since I belive those who are against mask wearing are also likely not vaccinated.
