I see many comments here every day that would get anyone instantly banned from most of the biggest subreddits. However, I think that most people would agree that this place is a lot less toxic than reddit. Smaller subreddits are somewhat better, but at this point this behavior has become pervasive in site, and users are expected to respond aggressively to any disagreement. As a result, any discussion becomes impossible and most comment sections are filled with users mindlessly agreeing with each other. Moderation is important but the way it is implemented in reddit has only managed to turn the site into an extremely toxic echochamber.
Reddit admins only set some very basic guardrails, typically around things like hate speech. Everything else is controlled by the mods. There are subs that are toxic and many that are not. Which you subscribe to is up to you and will determine your experience. The example often used here is /r/AskHistorians.
