Even if you present them with evidence of the demographic make-up of the region where Christianity & Judaism sprung from, they've been sooo conditioned & indoctrinated in the white supremacist frameworkkk that an African representation of the Hebrew patriarchs would not be able to penetrate their psyches - they'll go into deep deep denialism. I swear!
