Rudolph Giuliani making sure the laws were enforced in New York is an example that what Marx said is interesting?
Marx may have been “interesting” to the extent that someone who is completely wrong about the entire core of his world view is “interesting.” I found Mein Kampf interesting too, as a view into the mind of a racist lunatic whose world view was similarly dangerously and completely wrong. So in that sense, I guess I would agree that Das Kapital and the Communist Manifesto were interesting.
As for comparing city mayors to dictators, that simply waters down the meaning of the word. Let’s leave the emotional hyperbole to the progressives.
