Personally, I think slave moralities have much to recommend them, as movements against elite domination.

Intellectual culture has its own hype, like the computer world. Some with loudspeakers try to deify a few "great thinkers", focussing on (certain narrow aspects of) their personalities they wish others to emulate. Brushing others aside who don't fit their model, despite talent. (Like people with the wrong gender/race.)

Let's take another well-known philosopher (Chomsky), who pointed out how humanity's masters try to turn "great" figures into villains, when they act with exemplary slave morality:

"Compare Russell and Einstein, two leading figures, roughly the same generation. They agreed on the grave dangers facing humanity, but chose different ways to respond. Einstein responded by living a very comfortable life in Princeton and dedicating himself to research that he loved, taking a few moments for an occasional oracular statement. Russell responded by leading demonstrations and getting himself dragged off by the cops, writing extensively on the problems of the day, organizing war crimes trials, etc. The result? Russell was and is reviled and condemned, Einstein is admired as a saint. Should that surprise us? Not at all."
