In all seriousness I feel like the common answers I saw of Diogenes (because that was like, his entire shtick) or Socrates (because they killed him for being annoying) are probably better answers but saying its Trotsky on a leftist forum is way funnier.
Wasn't Stirner a fake guy made up for Marx to be mad at though?
Communism is when I do whatever I want, and the more I do, the more communist it is.
