You can’t be non-censorious and also take down hate speech, if that’s what you mean by “takes hate speech seriously”.

You’re either a censor or you’re not. If you want a censored platform, say it; if you want an uncensored site, say that.

The thing is, any service that offers a "censorship-free" alternative will instantly attract mostly by those whose content is garbage for everyone else: usually it's pedophiles until the operators get a couple not-so-nice letters or a police raid and then at least introduce modest moderation, and then come Nazis, antisemites and conspiracy myth peddlers.

And said hate peddlers then complain that they don't have the reach they enjoyed on Twitter, Youtube and Facebook... well d'oh. Turns out one who is not a Nazi, a journalist reporting about them, or an antifa activist collecting information wants to spend their free time on a platform dominated by Nazis.

This is a tricky problem even to define, because there's "Reddit" which is the owners and paid moderators, then there is "reddit" which is the universe of its subreddits and its unpaid, unaccountable moderators.

For example, it's been well known for awhile that if you subscribe to any of the men's rights subs, you are auto-banned from several of the feminism ones (including TwoXChromosomes). That kind of thing certainly isn't lenient but also isn't under Reddit's control.
