BLM coalesced as a reaction to police brutality and lack of accountability for how they treated black citizens. The organization claims its problems are rooted in the ghetto-ization of blacks that has robbed them of their agency.
Can I observe that both these problems are ones of an out of control, unaccountable, over-powered government? Police are government officials allowed to operate with few checks on their behavior. Black ghettos were explicitly created by the New Deal and maintained by Federal policy for years. No doubt many private citizens are still racist, but they can't legally shoot you on the street or say where you can and can't buy homes.
So why does the leadership of BLM so consistently support the further expansion of government power?
