If you invoked race as an explanation for e.g. why South Korea and Taiwan had similar modernization experiences, that would be weird but maybe not obviously wrong. Among the dozens of other similarities between these two nations, race as perceived by white Americans is one similarity. It's not the most salient similarity to reasonable people, but there's no inherent contradiction involved.

That's not what's going on ITT. China has had a different modernization experience from the other nations discussed above, which is entirely understandable given their very different histories, assets, infrastructures, populations, demographics, educations, etc. Your racism is that you ignore all those obvious differences in favor of one trivial, contingent aspect in which to an ineducable white American they might seem similar.
