From the United States Supreme Court
“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. If there are any circumstances which permit an exception, they do not now occur to us.”
“Freedom to differ is not limited to things that do not matter much.
That would be a mere shadow of freedom.
The test of its substance is the right to differ as to things that touch the heart of the existing order.”
“To believe that patriotism will not flourish if patriotic ceremonies are voluntary and spontaneous, instead of a compulsory routine, is to make an unflattering estimate of the appeal of our institutions to free minds.”
The decision by the Supreme Court of the United States holding that the Free Speech Clause of the First Amendment to the United States Constitution protected students from being forced to salute the American flag and say the Pledge of Allegiance in public school.
