The discussion doesn't count in any manner? I can present an argument, it's not my word, it's statements you can find fault in that are general in nature, not just an observation that stands on face value.
You've barely demonstrated in any way how race is more expressive in nature than gender beyond one isolated example and generalizing that to suggest our taking race more seriously in particular contexts means it's necessarily as complex as gender, a concept that's arguably older in terms of the usage, particularly as applied to language.
And that was far before the historical usages we see conflating it with sex when they were historically distinct, the psychological idea of gender later, but the conflation before that not based in the understanding you seem to think that the words were synonymous when we have demonstrable fact that gender applied in the masculine/feminine sense, the societal/cultural aspects, particularly to language, rather than sex applying to the male/female, the biological aspects.
