Students have the right to free inquiry and free expression of ideas. Free expression is not to be restricted, unless its exercise interferes with the orderly conduct of classes. Students have the right to recite the Pledge of Allegiance and salute the American flag, but may decline to do so long as they respect the rights of others who wish to do so. Students have a responsibility for showing proper respect for those who wish to participate in the Pledge of Allegiance, in flag salutes, or in patriotic ceremonies, and to respect the customs and flags of all nations. Students have a responsibility for the content of their expression and for assuring that such expression does not interfere with the freedom of others to express themselves. They have a responsibility to avoid libel, slander, obscenity, profanity, known falsehood, and disregard for truth.
