A group of elementary and middle school students on a field trip to the Kentucky Science Center in Louisville walked away with more than just lessons about science. A Planned Parenthood staffer sent them home with sexually explicit “adult” coloring books. It contained a page called “Sex Libs” and explicitly talked about condom use. The Kentucky Science Center issued an apology and said that the Planned Parenthood staff was not authorized to do this. This underscores two important things. Age-appropriate boundaries must be respected when it comes to sex-ed. Second, Planned Parenthood’s poor judgment continues to surface. They should know better that it’s never appropriate to sexualize second and third graders, which is why many want to cut federal funding of this controversial organization.
