Liberia has little to do with the overall history of Blacks in the U. S. It was an externally imposed solution to the “race issue” and focused, primarily on free-born Blacks, within the context of the period of African enslavement. Liberia was not the idea of Blacks in the U. S., it was a white-supremacist imposed experiment!
The issue is that, by a process of cultural genocide (ethnicide), physical deprivation, infiltration, mis-education, and a sustained campaign of racist violence, that included rape, American policy and practice created a population of people that could not collectively conceptualize any option but to identify with its oppressor. The Civil Rights Movement was not a rational choice of an empowered rational actor with agency, it was a capitulation to naked-power. Had Blacks in the U. S. recognized the power that they did have, at that time, instead of following the delusions of a Christian Charlatan, they’d have sought to consolidate the power that did exist in their externally enforced segration, just as the European Jews did in their ghettos! Instead, they sought power in Jesus, i. e., superstition!
The weakness in this choice is, now, made obvious by the extreme maladaptive, anti-social, and criminal nature of behaviors exhibited by far too many Blacks in American society and the violent/death-cult nature of Black America’s most popular art-form!
