"Critical race theory is an intellectual bulwark against the propaganda of history. Multiracial democracy is a recent and fragile innovation in American history. Those who think this fact has no place in our schools would- intentionally or not- hasten a return to unquestioned white dominance. We should never forget that it took National Guard soldiers to get black and white kids seated together in American schools, that abstract notions of a colorblind Constitution weren't a shield against slavery's horrors or the savagery of lynching, that Jim Crow was a legal regime codifying racial subordination, and that civil rights wrested from white supremacy's stingy fingers could be wrested back."
