Reading Nelson Mandela's autobiography now. He's in prison in apartheid SA in the 60s, in horrible conditions, enduring forced labor, with one prison guard who has a swastika tattooed on his wrist. And he's talking about how the ANC prisoners would treat individual guards differently based on how they treated the prisoners. He mentions a series of conversations with one guard where the guy asks what the ANC is about and is surprised to learn it's not a bunch of terrorists who want to kill all white people.

The contrast between that and the modern online sentiment of "everyone remotely associated with the crimes of capitalism deserves to die" is stark. Not everyone will come around, but a lot can. And even if you don't bring them all the way to good positions, there's a difference between an opponent who genuinely hates you and would die for their cause and an opponent who merely dislikes you, and who would choose to go home and grumble rather than fight to the death.
