So if a person advocates (for example) murder on an American site, this is fine until the police say it isn't? That is not a standard that 99% of the internet follows, and for good reasons.
The US legal system is 100% wholly incapable of keeping up with the pace of internet content for this sort of thing, so embracing the spirit of the laws on speech and applying them within user-content-based-sites is an appropriate minimum.
Even Musk who wanted to turn Twitter into a site dedicated to free speech specifically said he wanted to focus primarily on moderating content based on US laws (something that he has apparently walked back since then since Twitter still aggressively moderates legal content).
That's the whole point of Section 230. Service providers generally have immunity with respect to third-party content posted by their users. If a user posts something, it's their speech, and the user is therefore held responsible for it, not the website. Section 230 is what makes an internet of user-generated content possible.
