The only problem here is that China and Russia are also deeply racist against non-Han/non-white, respectively. (q.v. Uighurs, Tibetans, Chukchi...) More important is that this isn’t just a matter of racism specifically, but kyriarchy—a webwork of interlocking hierarchies. Not just racism, but also classism, nationalism, ageism, sexism, ableism, and so forth.
Like it or not, Russia and China are just as kyriarchical as the United States and Great Britain, and just as unworthy of your adulation. Denounce the authority of the First and Second Worlds alike, and bolster the Third World against them both.
