The problem with this, is that people sometimes really do, objectively, wake up and device to be irrationally evil. It’s not every day, and it’s not every single person — but it does happen routinely.
If you haven’t experienced this wrath yourself, I envy you. But for millions of people, this is their actual, 100% honest truthful lived reality. You can’t rationalize people out of their hate, because most people have no rational basis for their hate.
