Yes. The left has gloried in throwing violent threats around for years, and every protest they’ve held has been accompanied by violence-Occupy, Antifa, Black Lies Matter, etc. For that matter, all the way back to the 60s. And far from condemning their violent cohorts, they reward them-see Bill Ayers, Angela Davis, etc.
And either the Left has completely ignored the 1954 attack on Congress by the Puerto Rican terrorists which wounded 5 Congressmen, or has hailed them as “Freedom Fighters”.
