How do we have freedom?

Answer: The first amendment

Explanation: In the United States, freedom of speech and expression is strongly protected from government restrictions by the First Amendment to the United States Constitution, many state constitutions, and state and federal laws. The Supreme Court of the United States has recognized several categories of speech that are given lesser or no protection by the First Amendment and has recognized that governments may enact reasonable time, place, or manner restrictions on speech. The First Amendment's constitutional right of free speech, which is applicable to state and local governments under the incorporation doctrine, only prevents government restrictions on speech, not restrictions imposed by private individuals or businesses unless they are acting on behalf of the government. However, laws may restrict the ability of private businesses and individuals from restricting the speech of others, such as employment laws that restrict employers' ability to prevent employees from disclosing their salary with coworkers or attempting to organize a labor union.
