One glaring difference to me is that back then there was an and game. End the war and bring the troops home and there is not further need to protest the war. Since Occupy WS there had been no goal. Nothing you can do will end these riots. The insanity that has gripped the minds of young folks is just an endless churn of disjointed thinking that has no real goals. Systemic racism is fake and therefore you can never end it.
