From Kyle Olson's post on BigGovernment:
A radical organization known as the Pacific Educational Group (PEG) is actively promoting Derrick Bell’s Critical Race Theory in public elementary and high schools nationwide, with an intense focus on what PEG calls “Systemic Racism.” [...]
PEG has triggered local opposition, and occasional alarm. As long ago as 2007, organizations such as the Competitive Enterprise Institute have dismissed Singleton, saying  he has “become a rich man by preaching racism, hate, and scapegoating” (original links):
Previously, Singleton embarrassed the Seattle Schools. In 2002, they hired him  to indoctrinate their students and staff about racism . As a result, they redefined racism consistent with Singleton’s extreme and radical beliefs. The Seattle Schools defined “individualism” as a form of “cultural racism,”  said that only whites can be racis t, and claimed that planning ahead (“future time orientation”) is a white characteristic that it is racist to expect minorities to exhibit.
