"If there is any fixed star in our constitutional constellation, it is
that no official, high or petty, can prescribe what shall be orthodox
in politics, nationalism, religion, or other matters of opinion or force
citizens to confess by word or act their faith therein."
Minersville School District v. Gobitis, 1940
(or West Virginia State Board of Education v. Barnette, 319 U.S. 624 (1943))
