How is it that Hitler’s eugenics program flipped, and now the secret societies are promoting race mixing?

This is the question that arises after I finish listening to the 41st episode by Bill Cooper in a series called Mystery Babylon, all about secret societies.

In that last episode, he seems to be intimating a connection between Himmler’s SS and the United States Secret Service.

Any recommendations from Anon’s on what to listen to from HOTT next?
