Part of the monologue is stupid. Our youth and ignorance against mores of the past is just a bad analogy. I agree completely with his take that humans suck. As i have said a gazillion times whoever holds the power is the fuckor and whoever is without is the fuckee. Blacks no better than Whites. etc.
I do not accept cultural relativism. We should not simply give a pass cuz…so and so was just following orders, because they all had slaves, because others were participating in a mass rape. etc. It is not even true for instance that ALL contemporaries of bad actors were copascetic with slavery, genocide, rape…etc. Sure, there are a great many mindless followers. On the other hand there are a coterie of humans in which their birth dates will not cause them to be mindless and simply accept it cuz everyone else is doing it.
