Daren:

The link to the Seattle schools page appeared on the Mises Institute listserve with the following section excerpted:

*/Cultural Racism:
/* Those aspects of society that overtly and covertly attribute value
and normality to white people and Whiteness, and devalue, stereotype,
and label people of color as “other”, different, less than, or render
them invisible. Examples of these norms include defining white skin
tones as nude or flesh colored, having a future time orientation,
emphasizing individualism as opposed to a more collective ideology,
defining one form of English as standard, and identifying only Whites as
great writers or composers.

So I think your observation definitely captures the point.
