Yeah, I did. The author uses political violence as the term throughout. The problem here is not what the author means but that they're not directly addressing it in clear terms.
You had to guess/ask whether I read the article because the headline makes the source of the political violence ambiguous.
you can bet that an author pointing out a rise on the other side of the political spectrum would not go for muddy terms. This headline seen by a right wing person would just be something they would not click and assume it's reassuring their fox news world view by a different outlet.
