People laugh at Maoists a lot because they're often too zealous (like that group that wanted to wage a guerilla war with 2-3 person cadres in the Everglades) but they're the most theoretically rigorous and committed organizations. I think that they're right about pretty much everything even if they are about 50 years ahead of where the rest of the proletariat is.

Edit: Every time I think of Maoists I remember this one manual I read by some org years ago where they say you shouldn't use drugs or alcohol because it would hinder you contribution to the revolution, except if you need to in order to build the mass line (like going to bars to be with the workers). I also think of when the Red Guard (is that what they're called?) in Texas was protesting outside DSA meetings for being social fascists.
