I am paraphrasing a phrase that was attributed to Engels: “Socialism or Barbarism”. I do not think there is a problem in using barbarism for the likely return to tribalism in the case of capitalism falls for itself, it has a problematic etymology, (like vandalism, for example) and it was widely used in a racist way, but I do not believe that using it, with the meaning defined in Origin of the Family, has any impact on the permanence or absence of racism.
