> We're already forgetting the more important lessons of not designating internal citizen groups as the out-group (if we ever learned it) and not building up those registers labelling for one bad government to use. I don't think that's even the lesson. That's too detailed. That's not what happened in Cambodia or China. It's not what happened in Indonesia. It's not what happened in the Ottoman Empire. The problem is the same everyhere: how_wrong_you_are_about_facts * power * conviction, these are the three variables that multiply together to produce mass killings. Mao didn't have an out group (well.. that wasn't the big death toll at least). Mao didn't have registers. He just made people destroy the farming and millions starved. We have to care about truth. Then we have to limit power. Then we have to be doubtful about what we know so we make small changes and slowly.
