I looked at these articles:
Reflections of a Chicano Brown Beret
Palante! A Brief History of the Young Lords
Ideology of the Young Lords
I learned that the Brown Berets are still operating, after a long hiatus. I hadn't realized that, or that they have taken a leadership role in stopping violence within Chican@ communities.
I also learned that according to at least this one publication of theirs, the Young Lords had a big focus on learning history. The publication broke down dialectic materialism. I'm still not sure I totally understand it, but I feel a bit closer.
