On January 20, Inauguration Day, white nationalist Richard Spencer was knocked to the ground in Washington, D.C., by a masked protester. He filed a police report the following day, and posted multiple tweets about the incident, including this one:
If law enforcement can't protect us from antifa assaults we will begin protecting ourselves.— Richard Spencer (@RichardBSpencer) January 21, 2017
Antifa is a truncation of “antifascist.” (It’s pronounced with the primary stress on the first syllable.) The word has roots in early-1930s antifascist movements in several European countries, including the German Antifaschistische Aktion. The German group was forcibly disbanded by the Nazi Party in 1933; it was revived in the 1980s.
