Why not? Out of spite?

"If a person who provides classroom instruction in a public school engages in speech or conduct that would violate the standards..." The way this is worded makes it sound as if public school teachers risk being fired for violating FCC standards at any time -- even outside of the classroom, away from school or at home. Like, they could fire you for cussing at the bar after work, or stepping out to grab your paper without making sure all your bits were properly covered.
