So many things to touch on here. First, calling those who protest against the genocide in Gaze "performers who aren't seen by anyone" is just a result of the intense alienation of late capitalism / imperialism. The nihilistic capitalist feeling that nothing we do matters makes those who care appear to be freaks to those who don't care. Community is replaced by detached, sarcastic snark.
Second, the commenter blaming pro-Palestine comments on Russia and/or bots is just the icing on the redditer cake.
Third, saying that protesters are "exacerbating the problem," and not acknowledging that the IOF, the countries supplying weapons to Israel, or everyone else who refuses to do BDS are the ones actually exacerbating the problem is one of the worst case of ignoring material reality in favor of pure idealism that I've ever seen.
This is basically just a recitation of liberal left-punching as old as liberalism itself. Per liberalism, every disruptive social movement is, at the time, too extreme and counterproductive. A few years later, liberalism claims to have always been on the side of that movement and takes credit for it. At no point are the liberals repeating this doing anything other than a defensive recitation. They do not really have or believe in morals or politics as a real-world struggle.
Good point. Those who protested against the Vietnam War were slandered as long-haired hippies. John Brown was called a terrorists for trying to end slavery by the most effective means.
