No - you're not paying attention. Already posted in this thread or in a thread linked on this thread is the origin of the flag. And the link to the Kwanzaa Information Center of melanet has a description of its origin.
It was invented around 1920 by racist, black nationalist (the father of the movement) Marcus Garvey.
While it may have been used by several black nationalist gangs in the 60's (Black Panthers and US) it was not invented by them.
Here's what I posted: And I think it may have been the 'Black Panthers' or Black Muslim flag in the 60s.
Nowhere did I state that they 'invented' it.
