You are missing my point. Once one side decides the other is evil, it stops being about right and wrong (in the sense of objectively correct or incorrect). Re

You are missing my point. Once one side decides the other is evil, it stops being about right and wrong (in the sense of objectively correct or incorrect). Re-read this: > If one side has (say) convinced itself that the the other side is evil and duplicitous then this no longer works because 1) everything the other side says is viewed through the lens of evil and duplicity and 2) this evil and duplicity needs to be combated by any means necessary, up to and including presenting arguments that the first side knows are wrong but which it believes in good faith could allow it to prevail against evil and duplicity. and pay particular attention to the passage that I highlighted here.
