There's no smart algorithm for sorting posts, and there's a limited number of active threads, so it's not rage baiting in quite the same way. Only active threads stay alive though, so it has the exact same issue as twitter and other social media, only engaging content is served to users, and the most engaging things are rage bait, conspiracy theories, and porn. Things that get someone riled up enough to respond.
I am a liberal and also genuinely find many 4chan boards less politically awful than current Twitter most of the time.
The chronological sorting at least offers some diversity of opinion. The first 50 replies to a 4chan thread about Trump (in the right board) will usually contain many, maybe even mostly, anti-Trump posts. On Twitter you usually need to scroll through the sea of blue checkmark replies for a while to find even one anti-Trump post.
Some 4chan boards are majority neo-Nazis who want all minorities expelled or murdered. But stumble across a particular Twitter thread and it's the same thing but with even more ideological uniformity within the thread, and with 4000 neo-Nazis in the thread instead of 60.
That said, both sites definitely are not great to use if you aren't very right-wing.
