Look at Star Wars - that's how The Emperor took over the universe. Create an emergency which then creates chaos and the people will willingly give up their rights to feel safe and secure. Then you take over with little or no opposition.
And don't forget, George Lucas (who wrote Star Wars) is an uber-Leftist. He called Obama a “Jedi”.
Leftists CAN BE AND ARE Fascists! The Nazi party was the “National SOCIALIST Party” - they were leftists, not right-wingers.
