Which political views would those be? Most of the politically-incited violence of the past few years has been left-wing. From Antifa, to the Berkeley riots, to the BLM riots (and BLM-inspired cop executions in Houston), and the "Bernie-bro" attempted assassination.
If you know a good replacement, please let me know. That's worldwide data, but even using worldwide data, there just aren't that many violent Nazis out there.
I'm actually quite certain that antifa has either been infiltrated by agent provocateurs or is populated by useful idiots. I say this as a life long Republican (until March '03).
Edit: Am I supposed to summarize these 4 articles in order to be considered adequate response to a wiki link of an org that was dissolved 5 years ago?
