Hang on. The BLM movement isn't orchestrated like some sort of 60'ies negro Illuminati. All blacks in USA have ample reason to be pissed off. Some are more angry than others. There will be a bell curve. Saying that the entire movement is defined by the less gifted members of their community isn't fair. For the reason it isn't fair to define all atheists by what trolling idiot atheists say in theist forums.
Well, do you mean Black Lives Matter the actual organization, or the hashtag on Twitter, or something else?
People seem to have a terrible difficulty distinguishing between these three - and I don't mean you, Zoidberg.
But I've seen (and I won't bother to point out) folks saying "Black Lives Matter believes in segregation.", and as evidence, they'll literally looks at a sheet and read "The New Black Panther Party calls for five states to be owned by black people". Or they'll play that small group screaming "What do we want!? Dead Cops!! When do we want them?! Now!!" with no idea that this is, again, an entirely seperate group.
So, first, instead of some kids who use a hashtag once in a while, let's be clear. What actual, time-and-money connection to these assholes have to Black Lives Matter?
