It has started. The Posobiec book (foreword by Steve Bannon) makes the case that anyone to the left of Mussolini is a "secret communist revolutionary" and rationalizes doing anything to "crush" us.

This is a popular book. I found my own mother reading it. I took the title at face value at first and found the skull disturbing but not threatening what with not being a communist or anything close to it. But then I started reading and I realized that it's not a matter of if they pull the trigger but when, and when they pull the trigger that they would be completely comfortable calling my mild liberal beliefs communist, and that my mother would probably believe them as they stripped me of citizenship and sent me to a labor camp in El Salvador.
