> True free speech is valued because it fosters debate, and allows bad speech to be rebutted by more speech. A marketplace of ideas, and maybe more importantly, the counterspeech doctrine, are incredibly important principals in justifying the existence of free speech.
No, you're missing the phenomenon of gish galloping[1]. Toxicity will overwhelm the community because it takes no effort to spew disgusting nonsense and spam while it takes significant effort to rebut it. The mythical "marketplace of ideas" only exists in presence of moderation, whether somewhat decentralized like HN or like the iron fist of places like r/AskHistorians. A literal free marketplace of ideas is a cesspool.
