I won't get into the larger point your comment is making about power structures + definitions as I don't know enough about those histories to get into your assertions, but wanted to point out that the parent comment didn't seem to suggest these discrepancies were "biologically inert" as you were refuting (I'm also assuming you meant "inherent"). They were commenting on the a racial difference in educational outcomes. From my understanding that's largely a systemic issue, and regardless of shifting definitions/categorization, not a conversation about biology anymore.
