Your whole argument is BS. The 1th is not that you have the unlimited power to say whatever you feel like, and that your government cannot make laws restricting you to say whatever you want. The 1th is about political speech and freedom of religion. The 1th does not give you the right to incite hate speech or incite any form of crime or cause any form of harm. Your rights ends when they infringe on other people rights, and the government is elected to ensure the rights of all.
This sort of thing is exactly what the Bill of Rights is meant to protect us against.
You would be correct if the NSLs would prohibit somebody to excercise political speech or religion. But congress is perfectly in its rights to limit your free speech to protect other citizens rights. Like, you have no 1th right to shout fire in a crowded theater and thus cause a panic and maybe the death of some people. Or you have no 1th right to tell people to kill some other people.
You do realize that the 1th does not trump all the other ammendments of the constitution only because it is the first? That is why your government can arrest you for a crime, for example, and thus restricting your 1th, 2th, etc.
