I don't think it's a matter of understanding, it's a matter of identification. I recall when I was a kid, long before I learned about neurodivergence, I identified with Spock and didn't get when he was the butt of the jokes. one can also watch african wilderness documentaries and root for the crocodile to catch the gnu, or for the gnu to escape. I guess fascists and billionaires get what's going on in those movies and series just fine, it's just that they identify with the crocodiles rather than with the gnus, and maybe they don't realize that the criticism is aimed at them
