When Suzanne Young of Gilbert, Arizona opens her son’s high-school biology textbook, she sees a message that has less to do with science than it does conservative politics and religion. It’s a sticker that the Gilbert Public School District has forced all students to place in the book, supporting “Arizona’s strong interest in promoting childbirth and adoption over elective abortion.”

The message then goes on to support abstinence as the best form of birth control.

Shocked, Suzanne took to Twitter to spread the word:

This sticker is the final product of the school districts’ ongoing quest to alter science books to align with the area’s conservative values. Officials first pondered removing pages from the books, which turned out to be too expensive (and possibly illegal). The sticker, which students are instructed to add to the books themselves, proved the most economical choice (or anti-choice?).
