This post is solely about the British offshoot of Black Lives Matter, and no criticism of the original American movement is implied or intended.
It is apparent from the court appearances following the "Black Lives Matter" protest at London City Airport, that in Britain, Black Lives Matter is just the old Earth Liberation Front wearing blackface and its relevance to the rights and interests of black Britons, let alone black Americans, is nil. Just a gang of middle class white people trying to wrap the race issue around their longstanding extreme environmental agenda. Give them time and they will go back to their normal activities of digging up grannies and petrol bombing scientists.
