Everything depends on your definition of "peaceful". People "peacefully protest" all the time. They "peacefully" normalize assault and battery. They "peacefully" protect those who are violent.

From one perspective, everything since Bezmenov's admitted USSR spy actions meant to destroy the west with toxic ideology has been violent. By a different perspective, it's been "mostly peaceful": Only thousands dead, after all, and thousands isn't millions so it isn't "war" so it isn't "violent".
