decolonization means dechristianization.
it's not just about saying "they were wrong about heliocentrism and evolution and homosexuality and ..., but they had a sound moral system, and are fixing the problems".
no...
decolonization is dechristianization means overthrowing the entire order, and reversing the system at it's most critical points.
it's not just about leaving the theology behind, or filling in gaps. it has to be a total revolution in thought, to a more enlightened way of seeing reality, as driven by data and evidence.
