I get that you're responding to a different poster who's making a different point about a different study, and I happen to agree with you and the CDC on the "6 feet" thing. In principle, all us always should have understood that there's nothing magical about 6 feet vs. 7 feet vs. 5 feet. And we all should have understood that sitting indoors 10 feet away from a covid-positive person for a long period of time is a bad idea. So this isn't an attempt at a dunk or anything.
But if you hung out in this thread or followed the right people on SM, you were way ahead of everybody else. You knew it wasn't just the flu bro, you knew masks were a good idea, you unlearned the fomite thing months before everybody else, you knew it was safe to do whatever outdoors without a mask, you knew that lockdowns weren't all that costly, you knew the vaccines were really good, you knew that one dose of Moderna or Phizer was enough, you knew that vaccinated people didn't spread the virus, etc. Our public officials and/or the media (oh God, the media) failed all of these things at various points during the pandemic.
