Yet you have some friends on Instagram who post when they're out, and have seen some news reports (probably of the variety of "Japan's COVID mystery, why are their numbers so low?") where they hunt out some drongos in some dodgy tachinomya who aren't wearing masks for their story about how Japanese people aren't wearing masks either, and because it fits into your worldview, you'll glom onto that and post some non-peer reviewed rubbish that confirms your fervent wish that you shouldn't be in any way inconvenienced.
Oh look at that, I just saw the morning news. 115 new cases of COVID today in a country of 120 million during the Delta wave. It's a mystery I tell you. A complete mystery.
Don't listen to this guy, wear a mask, get vaccinated.
