“Now mathematics is being nudged into a specifically political direction by educators who call themselves ‘critical theorists.’ They advocate using mathematics as a tool to advance social justice. Social justice math relies on political and cultural relevance to guide math instruction. One of its precepts is ‘ethnomathematics,’ that is, the belief that different cultures have evolved different ways of using mathematics, and that students will learn best if taught… mathematics… is inexorably linked with the values of the oppressors and conquerors.”
In case anyone thinks this is too crazy to be anything but an elaborate joke, they even have textbooks teaching the stuff. This is why we homeschool.
