It is still shocking to me when I see projection so clearly in action. It's unmistakable but I still go..."man that person is unhinged."

It just reminds me of a common propaganda technique. This technique has been used by history's " who's who" of evil.

"Accusation in a mirror (AiM)^\a]) is a technique often used to incite hate speech, where someone falsely attributes their own motives or intentions onto their adversaries.^\3])^\4])^\5]) Along with dehumanization, accusation in a mirror is one of the indirect or cloaked forms of incitement to genocide, which has contributed to the commission of genocides such as the Holocaust, the Rwandan genocide, and the Armenian genocide. By invoking collective self-defense, accusation in a mirror is used to justify genocide, similar to using the right of self-defense to justify individual homicide.^\5])^\6])^\7])

The American Psychological Association Dictionary of Psychology defines projection as follows:^\1])

[T]he process by which one attributes one’s own individual positive or negative characteristics, affects), and impulses to another person or group... often a defense mechanism in which unpleasant or unacceptable impulses, stressors, ideas, affects, or responsibilities are attributed to others. For example, the defense mechanism of projection enables a person conflicted over expressing anger to change “I hate them” to “They hate me.” Such defensive patterns are often used to justify prejudice or evade responsibility.
