Law enforcement has always been used to regulate speech. You are not allowed to make false claims to sell a product or service; You are not allowed to yell "fire!" in a crowded theatre.
It is unconstitutional in the US for the government to regulate political speech. That makes authoritarians like you sad.
There's no mention in the constitution of protecting "political" anything.
The US Constitution prohibits Congress from making a law abridging the freedom of speech; And yet this has been ruled not to prohibit speech of certain kinds and in certain contexts. Fraudulent advertising of goods is illegal, and you won't get far trying to defend such fraud in court by claiming the protection of the First Amendment.
Indeed, you would probably find yourself on contempt charges as soon as you responded to "Do you swear to tell the truth, the whole truth, and nothing but the truth?" with "No, because that would infringe my constitutional rights!"
Your pseudolaw is no more convincing than that of the Sovereign Citzen movement.
