I don't know what kind of fantasy world you live in, but peaceful change doesn't usually happen because those in power generally don't want to agree to change out of the goodness of their hearts. I mean, you wouldn't condone arson, looting, destruction. How the **** do you think your country was created? Boston Tea Party involved the destruction of almost 2 millions dollars(in today's money) worth of private property.
Oh, but you stand by the reason, right? You agree with need racial justice? You just want to see it happen without anything unpleasant. And if it doesn't happen, what then? At which point is it okay to engage in violence, and how in the world do you figure that point hasn't been reached in the US?
Non-violent resistance is nice optics, but it hides an uglier reality. Dire Straits playing for Mandela and US college kids carrying placards saying "Divest from South Africa" looks nice on TV, but it was the deteriorating security situation that made the regime realize they needed to end Apartheid. That meant violence and destruction, else South Africa might still be minority ruled.
If you really, really believe that a cause is morally right, then you should support things a lot worse than looting in order to see it succeed. And perhaps not make moral equivalencies of the "there were good people on both sides" variety.
