It would be nice if society could develop some kind of technique to use in these cases of "we live in different realities". It sucks to have to write a guy off just because he lives in a different filter bubble than you do, yet I currently don't see any other option. And it seems like an issue that's growing in size.
Especially when the other guy “lives in a reality” where he thinks violently victimizing you is fine. It’s almost as if we need some way to separate from such people.
