Hubbard also blamed psychiatrists, allied with the tyrant Xenu, for carrying out genocide in the Galactic Confederacy seventy-five million years ago. There are obvious parallels in this legend with the Nazi regime, which used doctors, including psychiatrists, to carry out the extermination of the mentally ill, along with homosexuals, Gypsies, and Jews; and also by the Soviet government, which employed psychiatrists to diagnose political dissidents and lock them away. Hubbard lived through these shameful events, and they no doubt colored his imagination.
