Revolutionary defeatism means opposing your own nation, not “both sidesing”. In effect, that means lesser of two evils thinking is inherent to revolutionary defeatism. I get if you are allergic to moralistic phrasing of the concept, but it does ultimately come down to destroying ones own empire above all else because it's what you have understanding of and any ability to influence. Which, when speaking of global events, de facto forces any Americans or westoids to first and foremost prioritize targeting "the greater evil" of the Anglo-American empire.
