You are highly misinformed if you're talking about the original Black Panthers. "The New Black Panthers" however have absolutely zero ties to the original group and are a bunch of pieces of shit.
The original Black Panthers was based on socialist ideology and were about CLASS warfare, not race. They worked with all groups including whites, asian's and latino's. After they were completely destroyed by COINTELPRO, sure there were a few former members who were completely lost and went aloof, doing weird and bizarre stuff, some racist. But at it's core, at it's beginning and at their height, they were a socialist organization who recognized that classism was the real problem. It was very early on ('67) they completely rejected black nationalism and focused more a "revolutionary internationalist movement". Their emphasis was a Marxist-Leninist doctrine with a lot of Maoism. This is why every Party member had to study Mao Tse-tung's "Little Red Book" to advance his or her knowledge of peoples' struggle and the revolutionary process.
