Indeed. I do not want elementary aged kids sexualized and while I never want to deny adults their right to choose their partners, I insist on not changing textbooks and reading choices for children. What were they going to do, remove all the books that showed hetero couples, because "that would be discrimination"? SORRY. Homosexuality is not the standard and it's not something kids need to know about. Kids can accept that families all look different without an explanation about sexual preferences.
You're too late!
