The French authors listed at least had a sembalance of value from their works. Hell, I'd highly recommend everything Arendt wrote and Derrida wrote at least one good book on the Marx/Stirner rivalry. Plus if you're getting a philosophy degree you basically need to read everyone on that list (okay maybe exclude Foucault cus he says some dumb and anti-historical shit about leprosy)
But this piece failed to really get at the heart of Charlatanism. What really scares me are the "academics" who unironically believe in psychoanalysis today. It's not just for fashion - it's pure lunancy. These are your "lacanians". Try reading Lacan, or Deleuze and Guattari and you will see a whole level of bullshit one wouldn't even imagine possible. Seriously the story of Jacques Lacan and his popularity today among academics should scare you.
