(unfinished work)
Trots, Gonzos, Maoists and Hoaxists are all Ultra-left variants. (placeholder, needs references from Lenin's left-wing communism, an infantile disorder)
Gonzalists are a variation of Maoism.
Hoxhaists are pro-Stalin dogmatists
Trots are Wrong. Lenin is Right. "Marxism-Leninism is the theoretical tradition of being more Marxist than Marx. Western Marxism is the theoretical tradition of trying to be as Marxist as Marx and always falling short. Nobody is exactly as Marxist as Marx except for Marx, but you can be more Marxist than Marx"[1]
Maoists cherry pick Mao and worship it like a cult/religion. Ironically, most Maoists stop being Maoist when they read Mao in full.
