I think most superficial interpretations of anarchists are based on edgy LARPers rather than real political ideology.

Fun fact: Anarchy means "without rulers", not "without laws" or "without social order". There's a wide diversity of political thought under this umbrella, but the key underlying common denominator is (on some level, at least) a rejection of hierarchy (and often a rejection of capital).

Though it's fun to imagine what the philosophical and political beliefs that underpin a colloquial understanding of the word might look like, the answer is usually simply: Teenagers.
