Katherine Kersten warns us that as governor, Tim Walz brought in a K-12 ethnic studies infused with critical race theory to Minnesota (“Tim Walz Brings ‘Liberated’ Ethnic Studies to Minnesota,” (Aug. 21).

One of California’s available curricula, the ‘Liberated’ Ethnic Studies, likewise promises to critique “cisheteropatriarchy” and “anti-Indigeneity.” This curriculum endeavors to turn students into members of the social-justice “resistance.” Some school districts have used this approach to deliver one-sided lessons on Gaza and the conflict between Israel and the Palestinian Arabs.

In some cases, for example, Hayward and Pajaro Valley, school boards and community groups have pushed back against the Liberated curriculum. A nonprofit has sued the Berkeley Unified, Mountain View-Los Altos Union and Hayward Unified school district to obtain background materials on its proposed ethnic studies course. In Palo Alto, parents have gathered 1400 signatures. They are concerned that too much of the Liberated curriculum will be adopted and have requested a pause. Their story made the front page of the San Francisco Chronicle.

Because the ‘Liberated’ curriculum is so far to the left, some parents want to use instead the curriculum approved by the state board of education. Yet this official curriculum also follows critical race theory. It wants students to adopt and use the woke concept of “intersectionality.” It attacks the ideal of equal opportunity and hard work as an oppressive “dominant narrative.” It specifically attacks Asians Americans’ work ethic and stress on education.

Neither of these curricula should be used in public school classrooms. Both are unbalanced and hopelessly full of indoctrination.
