Close encounters of the racist kind is a good read. Here's the most relevant part:

Consider the H2 series “In Search of Aliens,” which, before its demise, promoted the work of Jan Udo Holey, a German writer whose antisemitic books have been banned across Europe. (Holey’s pen name, Jan Van Helsig, is a blunt Dracula reference, i.e. Jews are bloodsuckers.) The History Channel’s long-running series “Ancient Aliens,” meanwhile, features David Childress, whose books cite and build on the work of James Churchward, who promoted an ancient empire called the “lost continent of Mu,” whose “dominant race” was an “exceedingly handsome people, with clear white or olive skin.”

The history channel is entry level nazi propaganda.
