But the best one, to me, is when we go back at the very root... "You're a conspiracy theorist like those who believe the moon landing was faked if you don't accept that it's a pure coincidence that the outbreak started in a market next to a lab known to do gain-of-function research on modified bat viruses".
That tune changed too and, at least, discussing the lab leak possibility became acceptable.
It's all seriously WTF. I got two Pfizer shots but I always fought for and respected those who didn't want to get the shot.
And with all the evidence out now and all the countries saying: "We don't recommend a fourth shot if you're below this or that age", I certainly don't plan to ever get a third shot.
It's not a bad thing for experts to change their opinion as new evidence comes out.
