It is not up to the department of Education to determine the moral judgments that should be made in an individual student's life.  This is the job of parents.  Plus the proposed materials violate the religious and moral principles of many families and teachers should not be cramming these immoral ideas and philosophies down our throats.  This is Marxist and Socialist philosophy that we fought against in the history of the USA in order to make a better country.  Now you are claiming the right to throw it away.  It is shameful and morally wrong.
