It is a commonplace to say that slavery “dehumanized” enslaved people, but to do so is misleading, harmful, and worth resisting.
I hasten to add that there are, of course, plenty of right-minded reasons for adopting the notion of “dehumanization.” It is hard to square the idea of millions of people being bought and sold, of systematic sexual violation, natal alienation, forced labor, and starvation with any sort of “humane” behavior: these are the sorts of things that should never be done to human beings. By terming these actions “inhuman” and suggesting that they either relied upon or accomplished the “dehumanization” of enslaved people, however, we are participating in a sort of ideological exchange that is no less baleful for being so familiar. We are separating a normative and aspirational notion of humanity from the sorts of exploitation and violence that history suggests may well be definitive of human beings: we are separating ourselves from our own histories of perpetration. To say so is not to suggest that there is no difference between the past and the present; it is merely that we should not overwrite the complex determinations of history with simple-minded notions of moral progress.
