Sure, in the same way I appreciate Kant or Kierkegaard or any other modernist - as foundational thinkers who laid the groundwork for more contemporary ideas. The entire issue is that so many internet leftists take Marx as dogma, and are often poor students of philosophy outside of that very narrow context, yet will lecture you about how you only disagree with them because you haven't read enough year one polisci material. ML spaces are as dunning Kruger as the internet gets.
