The free exercise clause of the First Amendment protects the right to believe and practice any religion or faith of one's choice. It ensures that individuals have the freedom to worship and practice their religion without interference or obstruction from the government. This includes the right to attend religious services, engage in religious rituals or ceremonies, and observe religious customs and traditions. The free exercise clause does not, however, protect the right to say whatever you want or print your own newspaper, as those rights fall under the freedom of speech and freedom of the press clauses, respectively.
