Schools are already “drug-free zones” and “gun-free zones” — at least officially — and they have “zero tolerance” for all sorts of things. Sometimes this impulse to protect children can go too far, lending to a stultifying climate of political correctness. But nobody on the mainstream left or right disagrees with the principle that schools should be safe havens for children. And kids should be safe not just from violence, drugs, pornography, and sex predators, we agree, but also from more mundane threats, such as profanity and political indoctrination.
