A lot of stuff in internet comments is stuff that would absolutely never happen in real life. If you saw a hipster on a typewriter and a crowd of people bullying him in real life, it would be absolutely clear which behavior was worse. Plus, none of those people in real life would actually do any of the extreme things they write about in internet comments.
The whole thing makes me imagine a forum of the future. Maybe it's more like a physical forum or park in virtual reality. There's a story at the center and radiating out from it are avatars that have been left behind by commenters. The avatars would be run by an AI that has been briefed on what point the commenter wanted to make. Other users, using the forum live, could wander through the park and interact with the deposited avatars or one another. Bringing some elements of reality to the forum experience - i.e. making it look like you are in a public space and interacting with people, may also bring in some elements of civility that we enjoy in reality and not online.
