We should use mass AI propaganda to direct all our hate to an imaginary group of people that don't actually exist, and are distinct enough that no living human could ever be mistaken for one of them. Like, let's just invent an entirely new racial phenotype from whole cloth, with unique physical features no one has. And then just create a storm of AI stories, images, and videos of these evil bastards doing all sorts of heinous things. All of humanity can unite behind hating a group of people that don't actually exist.
If we're going to live in a post-truth dystopia, let's try using it for good for once.
