Back to teaching the 3 Rs.
Old textbooks never expire. Used mother’s old college texts when I could. The only thing that changed in a biology text was the pictures went from black and white to color. British Lit and Willy Shakespeare hasn’t changed over the centuries.
They may never expire but they do not cover the critical contributions of LGBTQs to literature, physics, mathematics, culture, philosophy, and so on. How will your child learn about fisting? How will they learn about the happiness that can be found after their gender transition is finally complete? About great leaders such as Stalin, Mao, and Pol Pot? How about learning situational ethics and relative morality? How about the evil nature of the white man and how he dispossessed everyone of everything and put them all in slavery or subjugation? How will your child learn about the world just from an old textbook?

Oh, yeah, did I mention the poor Palestinians?
