No, it isn't. The only limitations on Freedom of Speech is that it cannot cause harm to people. For example, there is a reason that we do not allow the Neo Nazi groups to go to give their rallies and protests in a place that is predominantly Jewish (especially with Holocaust survivors). We do not allow people to yell "FIRE!" in a crowded theatre. Etc.
Any other limitation of the freedom of speech is a terrible blow against our human (and American) rights.
