Quotes from article:

"A new database of nearly 900 politically motivated attacks and plots in the United States since 1994 includes just one attack staged by an anti-fascist that led to fatalities. In that case, the single person killed was the perpetrator.

Over the same time period, American white supremacists and other rightwing extremists have carried out attacks that left at least 329 victims dead, according to the database."
