I would argue that (major black political/cultural leader) got killed or whatever so that black people would have the freedom to act like whatever they want, as opposed to being required to act meek and servile at all times, but this song has a good beat and the animation is indeed beautiful.
The video would argue back that many blacks today have thrown away that aforementioned freedom by turning themselves into foolish caricatures for The Powers That Be. "Acting like whatever they want" doesn't quite fly when society rewards the ones that jump headfirst into the "KRAZY NIGGA" niche and ignores the rest. This is not universal, but nevertheless, this is the point, and over here is you.
