“AI is nicer than the average redditor” would be a more accurate title
I would say people on /r/amitheasshole are more biased towards the poster, i.e. nicer. There's plenty of those I've read where I thought it sounded like the poster was the asshole and the top replies were NTA.
Granted many of the OPs are very biased in the poster's favor. Most I've read fall into one of two buckets: either they want to gripe about some obviously bad behavior, or it's a controved and likely fake story.
