Not according to the Supreme Court:

"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.
........

Categories of speech that are given lesser or no protection by the First Amendment include obscenity (as determined by the Miller test), fraud, child pornography, speech integral to illegal conduct,[10] speech that incites imminent lawless action, and regulation of commercial speech such as advertising.[11][12] Within these limited areas, other limitations on free speech balance rights to free speech and other rights, such as rights for authors over their works (copyright), protection from imminent or potential violence against particular persons, restrictions on the use of unt***hs to harm others (slander), and communications while a person is in prison. When a speech restriction is challenged in court, it is presumed invalid and the government bears the burden of convincing the court that the restriction is constitutional.[13]"
