Western protest movements are intentionally coopted by liberal elements seeking to uphold the status quo. This doesn't mean they're never successful and pointless to engage in, quite the contrary, it's one of the major ways that true revolutionary energy is built. The western proletariat is just so housebroken and propagandized that any such energy that gets built up eventually dissipates when capital makes extremely basic concessions (see: George Floyd riots). I can see why that's discouraging, but that's how they want you to feel. Don't give up. Public demonstration is how we show our power.
