Here's an article listing fourteen defining characteristics of fascism. By Dr. Lawrence Britt.
Some high points;
-Disdain for the Recognition of Human Rights
-Supremacy of the Military (police in many cases)
-Controlled Mass Media
-Corporate Power is Protected
-Obsession with Crime and Punishment
ETA; -Identification of Enemies/Scapegoats as a Unifying Cause (ethnic or religious minorities among others)
ETA AGAIN; Commenter Captain Jack has done some research on the author of the article, and although Captain Jack agrees with many points in the article, the Captain advises caution about accepting all points as canon.
