Even if the research had come out that masks did absolutely nothing to protect against Covid, I would have absolutely no regrets for masking up. We did what we thought was the right thing based on the evidence available and it harmed no one. The worst that would’ve happened if we were wrong (outside of a false sense of security) is that we looked silly for awhile. The people that were vehemently against wearing masks were tool-sheds who were manipulated into their position by an Administration who assumed it would affect Democratic-leaning cities/states more and who are so blinded by their anti-science views that they didn’t even understand the threat posed by Covid. Mask wearers did the right thing and the evidence backs us up. Anti-mask idiots hopefully learned an evolutionary lesson, but I doubt it has really ever sunk in.
