Nietzsche literally moralized everything. His books were called "On the Genealogy of Morality" and "Beyond Good and Evil".
Dissecting morality isn't moralizing ? What are you talking about ? It's called "BEYOND" Good and Evil, right ?
But i see what you're saying. I think to be an academic, you can't be an activist. You need to look at things objectively, or else it becomes much easier to run into confirmation bias, and then your research is just worthless lies. From an academic sense, "Hitler did X and that's bad" isn't nearly as important as "Hitler did X because of Y and Z".
Well, I didn't think of it that way but what you wrote makes sense. I do think academics can be free to moralize, but their primary goal is to assess and provide a landscape for thought and discussion.
Peterson's perspectives on psychology are 1000x more interesting than his political views.
I actually think there's lots of room right now for a moralist of his ilk. But he isn't the guy.
