In the interest of fighting this sentiment within the left, I often try to step back and see how my ideology and my efforts fit within a world historical movement, the totality of all of the oppressed people united in their struggle for liberation. I think that there's something very important about understanding what we have in common, all throughout the world, and that we fundamentally believe in the same thing. I also think that liberalism and fascism are allergic to this unity, that they revile unity of purpose; they portray us as mindless drones, the gullible masses who don't know what's truly good for them.
It's also worth bringing up that we ought to combat the very common Masses, Elites, and Rebels view of the world that is particularly frequent among Western leftists. We are not special people among ignorant masses. We are not in They Live with the glasses that make us see through the propaganda. We are not mommy's little special children that are Very Smart and have a unique predisposition for seeing the Truth. We are just workers among workers.
