Normalizing The Lesbian Family- Kids' Books for Christian Kids

Why are kids books and movies picked up for Christian kids normalizing lesbian and homosexual families?  Why is this press to condition the kids so universal it is even employed in  books by favorite Christian kids author, Sally Lloyd-Jones? Toy Story 4 includes a homosexual moment, in an effort to normalize perverse relationships.  We define this "normalization," and then address the question, "Why do Christian pick on the sin of homosexuality over all the other sins?"
