I’m not trying to defend them. I’m trying to point out that you’re not defending yourself from that idea. In a world where all the nazis have been genocided, that is a world that accepts genocide as a reasonable solution. That world will commit another genocide and sooner than you might think. Especially when you consider that it didn’t start with nazism. There were confederates before them and there are zionists after them. If you accept one genocide then any other just has to find the right justifications. Recognizing human susceptibility to that idea is the first step in protecting yourself from it. If we fail to do so, the cycle will never end.
