The text you quoted, which is the same I originally referenced, is about classroom instruction. You are inventing an outcome that is not found in the actual text of the law, maybe because it fits a perception you have or a narrative about Florida. No one is contesting that it's normal for people to mention their private lives at work - though the context in which you do it is important, and proselytizing in any direction generally makes people uncomfortable - and the law does not forbid this.
