@vikorr,
A strict interpretation of the words in the First Amendment is that no speech is ever illegal, however, it really is necessary to allow punishment for speech in a tiny number of situations, but that number should be kept as small as possible. Expressing opinions, no matter how repugnant must never be illegal, however the law really does need to have a way to protect people from shouting "Fire!" in a crowded theater, or libel, or directing people to commit imminent violence.
You can keep asking me more and more questions in an effort to find a defect in my reasoning, if you like, but there is no defect and I'll just keep giving you the correct answers. It will be tedious to prove to you, but proceed if you must.
