"The data shows us, going back to the 1990s, that more plots, attacks, and deaths come from groups that are categorized as right-wing violent extremists; primarily white power movements and militia movements... The why behind this is murky... some of it is personality factos, the right tends to be much more organized than the far left.

The far left, which has a value system that they don't want anyone in charge, tends to destroy property, so you'll see them in riots. It's usually not a premeditated type of attack. We did have a significant set of far-left terrorism in the 1960s and 1970s...

The reason I wrote this book was because my side is responsible for more deaths and destruction than the other side and I feel a sense of responsiblity to clean our own house. Let's clean up our own house before we fear monger about Antifa and far-left terrorism."
