Establishment controlled groups such as “Black Lives Matter” are a part of an anti-black agenda of creating animosity and division (See this link and this link). Such agendas contribute to general animosity among races, such as when a Trump supporter was attacked in Chicago shortly after the presidential election, which the attackers recorded on video.
The video cuts out before it is shown that the car door was slammed on the man’s hand and the car drove away with his hand still stuck in the door. Also see this link and this link.
