It's not discrimination if it is against white people:)
What you've stated seem absolutely absurd to rational, normal, people. Take a look at what the school district's web site says - from the article - emphasis mine :
Until June, the school district's Web site declared that "cultural racism" includes "emphasizing individualism as opposed to a more collective ideology," "having a future time orientation" (planning ahead) and "defining one form of English as standard." The site also asserted that only whites can be racists, and disparaged assimilation as the "giving up" of one's culture. After this propaganda provoked outrage, the district, saying it needed to "provide more context to readers" about "institutional racism," put up a page saying that the district's intention is to avoid "unsuccessful concepts such as a melting pot or colorblind mentality."
