It has nothing to do with being offended. Free speech is restricted all the time
Hate speech, inciting riots, etc.
You're free to say whatever you want. No one will stop you, but you also have to face the consequences of saying those things. It seems like someone doesn't really understand what freedom of speech actually means. That's typical, most people take the self-centered view that free speech means they can say whatever they want without consequence. That's false and has never been true. Free speech only means that you can say it in the first place. You're free to change warcraft to doorcraft and giggle yourself to sleep with how clever you are, but if you infringe on someone's copyright then you have to face the legal consequences of that.
