Laws tend to be written pretty broadly, with the understanding that when you encounter a law that seems like it could be construed in a ridiculous way, it’s the ridiculous construal that is silly and not the law. Judges and juries exist to ensure that silly stuff doesn’t happen, rather than trying to write laws so that they hold up to the most adversarial possible reading.

Is writing a book about being a bank robber going to pass muster as a threat to public morals? Probably no. Is setting up a free cigarette dispenser outside of an elementary school? Probably yes.
