That was a close call. If the students had read that definition, they would all have tried it perhaps in class.
Now that they have been protected from the definition, they will never know, and will never, ever experiment with such things.
Now what do we do about the folks in the town who withdrew the dictionary? Perhaps they were influenced by reading a definition of “stupidity” in a dictionary at an early age, and it predisposed them to act it out in later life.
I am sure kids learn more from sexting anyway.
