In which case did the court rule that express conduct is protected under the First Amendment?

The court ruled in Texas v. Johnson that express conduct is protected under the First Amendment by affirming that symbolic speech is a form of expression. In this case, the Supreme Court addressed the issue of whether burning the American flag, as a form of protest against the government, constituted an act of speech protected by the First Amendment. The Court determined that the act was indeed expressive conduct intended to convey a particular message, thereby falling under the umbrella of free speech protections. This ruling underscores the principle that the First Amendment safeguards not only spoken or written words but also actions that are intended to convey a specific message.
