In this gallery of wide aspect ratio photographs taken on May 1, 2019 during the Immigration Politics Rally in Seattle, a tiny contingent of Marxist Communist Antifa Black Bloc domestic terrorists were present infiltrating the immigration and worker rights politics event. The Antifa Black Bloc is a domestic terror cell network well known for violent antics where ever and whenever they are present. The BlackBloc terrorists are known for wearing all black clothing that includes masks and other attempts to disguise themselves. The Marxist Communist BlackBloc espouses what has been described by some as "Anarcho Communist" political beliefs. The Antifa Black Bloc terrorists espouse politics that are an alt-left extremist version of radical violent revolution based Marxist Communism. The banners and posters displayed by the Antifa, so called "Anarchist" Black Bloc contains slogans such as "Anti-State" and "Anti-Capitalist" to describe their violent, seditious revolution based Marxist Communism. The photographs of the few Antifa Black Bloc domestic terrorists in this gallery illustrate the generally immature, if not infantile, behavior and antics the Black Bloc demonstrates as they act out with tantrums at political events. Ironically, one of the Antifa Black Bloc terrorists present on May 1, 2019 in Seattle didn't appear to have gotten the memo about wearing all black and was instead attired in a navy blue bandanna, canvas colored docker hat, and a blue, white, and black, checked button down shirt, with bright yellow work gloves on his hands. Based on the infantile gestures that the Black Bloc hooligans made with their hands, they tried to act like they didn't like being photographed, despite the fact that they repeatedly made a point of buzzing about and mugging for the camera the entire day.
