I'm not an authority, no. Never claimed to be. However, outside of the Zapatistas, I'm not sure I can even name a leftist movement that doesn't draw directly from Marxism or anarchism in the modern era. Marxism generally is heavily influential over those for full collectivization, while anarchism is heavily influential over those that seek horizontalism and decentralization. Groups that reject both are usually just social democrats that wish to retain capitalism.
