Insults? You should be able to (and protected to) insult anyone you please, at any time. Insult has to be taken. Insult is never given. There is no right to not be offended, and there should never be one, because offense/insult happen internally. You cannot insult me if i chose to not be insulted, you can not offend me if i chose to be offended.
False advertisement isn't about free speech - it's about making a verbal contract and not following through. You're free to say whatever you want, and the offence isn't in the saying it, its in the failure to keep the contract.
Society is rarely served by more restriction.
