Police across the United States are being forced to deal with a new hard-Left, communist-derived movement organized under the code word "Antifa," standing for "Anti-Fascist."

The violent, confrontational nature of Antifa anarchists presents a challenge to U.S. law enforcement that is unprecedented; they reject the free speech principles upon which civil discourse depends, while seeking to achieve the demise of the U.S. Constitution, as it holds as illegitimate any compromise with their communist worldview.

The Antifa movement roots in Weimar Republic Germany

While the Antifa movement is anarchic in nature, it owes its birth to the Communist Party's opposition to the Nazi fascist movement in post-World War I Germany.
