You say you don't, but you exclusively discuss positivity or progress w.r.t. China and socialist countries. When anything negative is reframed out of the equation, the resulting assessment necessarily becomes unilaterally positive.
Imperialist countries being a drain on the world isn't something I'm arguing against, although we do not share a common understanding of imperialism.
It's true that I don't believe analysis must be through the diamat outlook for it to be rational, though framing away negatives as metaphysical or any other framing that makes them to be other than what they are (i.e. negatives) isn't something that I find compelling.
