The Black Panther Party has openly called for indiscriminate killing of Americans simply based on their skin color.
They are by definition a terrorist organization centralized on US soil and have been operating for decades.
With the removal of the Confederate flag from government buildings, and the removal of anything with a confederate flag removed from major companies like Wal-Mart, ebay, and Amazon I find it only fair that merchandise from a racist, bigoted, terrorist organization like the Black Panther Party be removed and banned and law enforcement agencies take the appropriate action.
If we are to eliminate racism in America, it needs to happen on both sides.
