CNN insists that recent riots in Kenosha and Minneapolis were mostly peaceful. This might have worked on radio. On TV, not so much. Possibly the term has been redefined by CNN. Could be. In the CNN world boys are girls, girls are boys, and Biden has his shit together!
I guess if one buys off on the CNN characterization that looting, burning and rock throwing are mostly peaceful activities, then what follows is also true.
I hope I was able to put mostly peaceful into an usable context.
