It seems naive to imply the US has a less effective propaganda apparatus than Russia within its own direct sphere of influence. The idea that a country with 1/10th the GDP of the US outcompetes the US in propaganda delivery on its own pay-to-play media platforms doesn't make a lot of sense to me personally. Seeing any kind of anti-war dissent as influenced by pro-Russian agents seems like low-effort thinking. Being weary of an escalating proxy war with a high-manufacturing capacity, energy-rich superpower that historically has sacrificed large percentages of its population in total war is not inherently a pro-Russian stance; it's a common-sense stance that values life.
