No, the paradox of tolerance is relevant when you have radical political factions inflicting violence on the population and preventing opposing opinions, not when some small group of people has crazy ideas that have little-to-no impact on society as a whole.
The paradox of tolerance states that if a society is tolerant without limit, its ability to be tolerant is eventually seized or destroyed by the intolerant.
Crazy people thinking that the Earth is flat doesn't prevent you from circumnavigating it.
> Crazy people thinking that the Earth is flat doesn't prevent you from circumnavigating it
Crazy people believing that vaccines are a Democrat/BillG/CIA plot will prevent you from achieving herd immunity, if they are numerous enough.
Crazy people who think the Earth is flat will deny your circumnavigation project government funding, if there are enough of them.
In any organisation that is not a totalitarian autocracy, crazy people hurt the organisation's goals. The more numerous and organised, the bigger the gridlock.
Tattoo them, not implant. I believe that because billG said that’s what he wants to do, unless the official website is some sort of joke I’m not getting: https://id2020.org/
So don't debate with flat earthers. Nobody is forcing you to.
Anyway, you've listed three things and one of them isn't like the others. I'll give you a hint: hate anti-vaxxers or not, there have been vaccines in the past that had extremely severe side effects. That is an absolute fact. Everything from that point on is about risk tolerances, tradeoffs and group safety vs individual freedoms, i.e. things debated for thousands of years.
Lumping people who are scared of vaccines into the same category as people who think the earth is flat is the kind of tactic that makes so many of us think ... fuck it, just let everyone say what they want. Total freedom of speech everywhere. Why, because trying to institutionally determine what's "true" is a complete waste of time. Everyone who thinks it's easy ends up causing massive collateral damage by shutting down legitimate and important debate. See how Wojcicki at YouTube has been deleting videos of epidemiologists and Nobel Prize winning scientists for "misinformation". See how she's been forcibly upranking outlets like CNN in recommendations, even though people don't want to watch it and it makes Google lose money. See how Facebook has shut down groups for people who think lockdowns are a harmful policy. See how Google is now censoring "communist bandit" globally.
This kind of childish behaviour doesn't make the tech industry look smart, it makes us look like arrogant fools.
This is the paradox of tolerance. Some ideas are worth debating, some are not. We all have limited time and energy.
