My only qualm with your position in this piece is that Black Lives Matter isn't a monolithic group. The loudest and shrillest individual voices don't necessarily speak for the entire movement 100% of the time (even though they would have us believe that they do).

Furthermore, I think it's important to make the distinction that Prejudice+Power is specifically referring to SYSTEMIC RACISM. Social and cultural forms of racism don't require an institutional power component.
