There’s a lesson here.
If you’re running, say, a newspaper, and want the population to fear someone, you focus on identity and offer no other details not consistent with that identity; you fix the identity as primary. You don’t describe him, you declare him.
To make people hate someone, start from fear but then attack the identity. Offer otherwise irrelevant information that puts them not in a negative light– too obvious– but in a contrasting light.
To everyone else not intent on destroying our civilization to sell copies, there’s this advice:
When you find yourself hating someone (who did not directly hurt you) with blinding rage, know for certain that it is not the person you hate at all, but rather something about them that threatens your identity. Find that thing. This single piece of advice can turn your life around, I guarantee it.
