Based on the Supreme Court case tinker v des Moines, it would be legal for you to wear an amber to school in order to protest an action taken by our government if it did not create. What is the basis for this

Freedom to assemble peacefully
Establishment clause
Freedom to petition
Protected symbolic speech

The basis for wearing an armband to school as a form of protest, as supported by the Supreme Court case Tinker v Des Moines, is protected symbolic speech. In this landmark case, the Court ruled that students do not "shed their constitutional rights to freedom of speech or expression at the schoolhouse gate." Therefore, as long as the protest through the armband does not disrupt the educational environment, it is considered legal and protected under the First Amendment.
