IMHO, the reason they don't exist in the same reality is the anti-vax side made up their minds before the vax was even available and didn't look at the studies or data that became available; until the VAERs report became available, they really liked combing thru that data set. I'm fully aware of the side effects of Covid vax, so that info hasn't been censored - the data is on CDC's website. The links to the studies regarding negative side effects are on gov't websites. So I'm being told the gov't is censoring this information, but it's actually the gov't that is providing and disseminating this information. The problem I've had with every anti-vaxxer I've encountered is when presented with the mountains of data showing that the benefits of the vax far outweigh the negative side effects, I'm always told "they" are cooking the books. If that's true than the best we can do is guess and rely on anecdotal evidence and there is no common ground for debate because 1/2 the people you know got f'd up by the vax and nobody I know suffered any adverse effects...
Being Anti-vax is nutty IF one claims that position is rooted in science. Statistically, you're just better off with the vax than the covid. Now that Omicron is the dominate strain, I'd say who cares if you vax. But when Delta was killing people quicker than we could get them in the ground, the vax enjoyed a massive advantage over catching Covid. That's why I say don't censor the anti-vax stuff - just fact check them. That said, if there is one thing that ~35 years of following politics has taught me, it's that FACTS DON'T MATTER!!! When anti-vaxxers are confronted with studies, facts, data & stats that dispute their positions, they just make a hard right down conspiracy lane: I'm only seeing what "they" want me to see, "they" cooked the books (stats), the very fact that there isn't proof of their position just proves that there is a cover up. That's why there is no common ground; not because RFK isn't on youtube.
