The Nazis had their Untermenschen. Contemporary Republicans have their illegal immigrants. Contemporary progressives have their gun owners and users. Contemporary conservatives have their drug users and traffickers.
Everyone, it seems, has identified the members of certain groups as not people, but animals. Thus, dehumanization is the order of the day.
Pretty soon so many will have been dehumanized that the remaining three human beings will be able to sit down together and work out their differences peacefully without bringing down a hail of official force and violence.
