I think it was more people were like What's the fuck?, the mask only helps if I have it and I don't know it and it only protects others and not me? I feel fine, fuck it.
If from the beginning it was like "initial viral load matters, you die if you get a lot of it, and you don't if you get a little, and the mask helps make it a little" you'd have a different outcome here.
Nothing is or was going to get these dumb fucking anti maskers to wear a mask.
