A very small minority can be such a grievous pain as to make large systems of power unsustainable. You don’t need a majority to derail an injustice.
Many folks already know the score. All that’s holding them back from joining in active resistance is a sense of isolation, weakness, and despair. In this context street fighting and vandalism are not so much proofs of method but statements of commitment and seriousness. There are others like you who are willing to fight, and we can hurt them, or at the very least we can shatter the air of invulnerability that pervades business as usual.
That’s why politicians and police consistently go apeshit over things like measly storefront windows. Their control is dependent in no small part on being seen as in control.
