This is the danger of censorship of ideas. Even if they’re wrong and the people labelled kooks, free speech is extremely valuable: It’s not so valuable for the times the speaker is quite wrong… but it becomes critical in “iffy” cases where censorship can close off the right idea while leaving intact the “not entirely wrong but not quite right idea”.
This is why I’ll sometimes debate flat-earthers for example and other times just leave them alone. Why? From a pragmatic point of view, it doesn’t matter 99% of the time for 99% of the cases where someone might believe it. [99% is, of course, made up]
Here’s how I look at it: I haven’t left the planet. I’m not likely to leave it anytime soon. Whether it is flat or round or even if the Universe is part of a nearly infinite set of holograms dancing on the head of a pin….
..it doesn’t matter. Same with creation/evolution. Fun to talk about but ultimately not that big of a deal for most except perhaps to biologists who have to study the stuff for a living.
