Because protests don't do shit. There were mass protests over police brutality in 2020. Didn't do shit and the right wing media reaction arguably helped kill off police reform legislation that was in progress before the protests.
The reason protests from the left don't do shit is because the most popular media is controlled by Maga. The top social media network for news, the top podcast, and the top cable TV news are all outright maga propaganda. A narrative can arise without them, but they will determine what happens to it. So last time, the protests arose due to George Floyd, but the right wing media turned it into a narrative about lawless riots, using exaggeration and fake images.
