My teacher says there is a fallacy in this? Is there and what kind? thanks

The American flag, then, throughout more than 200 years of our history, has come to be the visible symbol embodying our Nation. It does not represent the views of any particular political party, and it does not represent any particular political philosophy. The flag is not simply another "idea" or "point of view" competing for recognition in the marketplace of ideas. Millions and millions of Americans regard it with an almost mystical reverence, regardless of what sort of social, political, or philosophical beliefs they may have. I cannot agree that the First Amendment invalidates the Act of Congress, and the laws of 48 of the 50 States, which make criminal the public burning of the flag.
