But you know what, Karl Marx, when I look back at history, I prefer the bearded communists. Let's talk about some communists who didn't have beards. Mao Zedong, Pol Pot, Kim Jong-il, Joseph freakin' Stalin with his face caterpillar. So yeah, Karl Marx's beard, it's my great regret to inform you that there are some paltry beards trying to take up the class struggle these days. Best wishes, John Green. Although he's often considered the father of communism because he co-wrote the Communist Manifesto, Marx was above all a philosopher and a historian. It's just that unlike most philosophers and historians, he advocated for revolution.
