"Primal Scream" can be very therapeutic, if balanced with a "Yin" introspection. I watched many people doing exactly that after the last election. (The screaming part, anyway.) Our instructor had us "shout" at every 10th repetition. My friend would sometimes shout prior to initiating an attack. He did it once too often and earned a broken nose for his effort. There's a time for everything, I suppose.
