Isn't the West trending back toward racism, nationalism, etc.? I feel like a lot of people thought history was over post WWII, but I really doubt that's the case......but you're correct that it's extremely hard to do credible counter historical analysis. There's so many little things. The Hitler of the 1960s could have been killed in London during The Blitz. The next Einstein might not have been born because his father was killed in Guadalcanal. Etc. etc. In light of this I really think it's hard to argue that WWII resulting in 60M dead is a good thing on a long enough scale.
I was seriously asking you what your parameters were on who is justifiably killed. Your initial statement was bizarre to me so I wanted to clarify your position. Your significantly revised position, which is that bad people who do bad things deserve to pay for those bad things, is completely accurate. Just wanted to point out that "black people killing those specific people who have committed bad acts against them" is very different from "black people are justified killing white people".
btw what were we talking about again?
