The profound psychopathology of the human race. Two-hundred-million plus people killed in the 20th Century as a result of warfare and genocide.

Yet no mention in the DSM-V of warfare and genocide as forms of psychopathology. Better: "Social anxiety disorder" (shyness). Fatuous.

The delusion that if something occurs regularly in human societies, it can't be considered psychopathology. It just "is." This is the way things are. Profound hypocrisy.

 Equivalent to saying that cancer is not a form of pathology because it occurs so frequently.

Profound denial at the heart of the human race. Denial (not rationality) the essence of what it means to be "human."
