What is the mechanism that your are proposing?
Rhetoric rhetoric rhetoric all day. Slogans and rhymes are not levers of power.
What is the mechanism? All I see, as Yunzer says, is idle fantasies about a 20th century-style vanguardist revolution.
Let's think about that, honestly, for just 5 seconds. Have you ever seen riot cops close up? I ask the question seriously, not flippantly. This is the first barrier to the Necharevian dreams of revolution the United States: there aren't many of you, and the cops will squish you like fucking insects. Forget rubber bullets and tear gas. You want to fuck with weaponized lasers and hollow points? That's what you're asking when you talk about change through "violence in the streets".
But let's say, somehow, you succeed, and now the State falls! Huzzah comrades! Well, now what happens? Are you prepared? You know who IS prepared? The right-wing paramilitaries that spend their weekends training for the collapse of the state. Guess what? They hate you. They hate socialism. They LOVE God and they LOVE guns.
You know what else they like? They like Order. They like Order, they like their Heritage, and they like Guns. You know who else like Order, Heritage, and Guns? Fascists do! So guess what, now you've got organized fascists paramilitaries that are armed and ready. Who do you think will form the new State? You and your Marxist book-club buddies, or the neo-nazi paramilitaries waiting in the wings?
And that doesn't even bring up the power of global capital that will come to bear on any fantastical post-revolution period. You think corporations have a lot of power now? Well who do you think can afford a better army: you, or Goldman Sachs?
You'd better fucking hope it doesn't come to violence in the streets, because WE DO NOT WIN when that happens. WE NEVER WIN when that happens. Look. At. History.
We've seen what vanguardism leads to: Russia, China, Vietnam, Cuba. We've seen what failed revolutions lead to: Syria, Iran. How much more evidence do you need to drop the myth of the glorious revolution bathed in blood? How many million deaths is it worth to hold on to the myths of the 19th century?
"Violence in the streets" needs to be avoided at all costs. Even if — gasp! — it means making compromises. We aren't negotiating from a position of strength. We are negotiating from a position of weakness. To threaten violence is just absolutely laughable. Laughable.
