Those aren't very good examples, because a) you're giving the conspiracy theorists too much credit and b) the facts changed. The vaccines were incredibly effective - against OG covid. Then the variants came along. Feel free to correct my memory, but the conspiracy theorists weren't being censored for shouting that the vaccine's theoretical efficiency was under threat from possible future mutations - they were saying idiotic stuff like that it's a government conspiracy to inject us all with mind control drugs.

I just do not understand why certain "left leaning" officials cannot accept they were wrong. It is how science works.

Just say - "we were wrong by claiming that vaccinated cannot spread COVID so we will lift COVID restrictions". Also since data shows that it is unlikely that kids will get sick we will lift mask mandate in schools.

But data clearly shows that "vaccinated people are less likely to get seriously ill". So please do get vaccinated. ASAP.

Very simple - just follow science and maybe, just maybe, you will be able to convert some people to belive the science.

Nobody de-platformed anyone that didn't give them that platform in the first place. They aren't entitled to a platform. It was a privilege abused.
