There are rules, Mr. Polite. The highest authority in the USA, the "biggest rules", are embodied in the U.S. Constitution. I cannot imagine a more direct violation of the right to free speech and free press than the ban you suggest. You should be immediately removed from office for even suggesting such a thing as an elected official. To do so would be not only heinous in its illegality, but monumentally offensive to freedom-loving Americans everywhere.
Resign your office and hang your pathetic head in shame, Mr. Polite.
