1) a small group of tyrannical oppressors currently in power
2) a large population being unjustly oppressed
3) a small group of reasonably comfortable people who are aware of the injustices but remain neutral because it isn’t directly affecting them *yet*
Zorro, then, is the story of someone from group 3 who makes the conscious choice to fight against group 1 and defend group 2, and ultimately must convince group 3 to shake off their neutrality and join his struggle.
If you swap "Zorro" for "The Buddha" and "fight against" for "enlighten" I think it still mostly works.
Yup, looks like I'm not the first person to have this thought.
