I visited the Civil Rights Museum in Memphis last week, on the site of where Martin Luther King was murdered. It has a large section on the Black Panthers and their legacy. It's one of the best museums I've ever visited actually.
It also tells of the progression in thinking of Stokely Carmichael, for instance, and SNCC etc to more radical positions. And enforces the point that at least these people did something, anything, they made a stand. Whether they succeeded is another thing but they stood up to prejudice.
Also on another point the Black Panthers were not anti white. They forged links with radical white and Latino groups.
