The U.S. has
many exceptions to free speech. Libel, slander, "fighting words" (see Chaplinsky v. N.H.), "imminent lawless action"(Brandenburg v. Ohio), obscenity (Miller v. California), etc. These have all been interpreted in varying ways throughout history, with the general trend being towards more protected speech (compare Brandenburg/"imminent lawless action" to Schenck v. U.S./"clear and present danger"). Additionally, the government can restrict speech further when acting in a special capacity, such as the FCC's regulation of the speech on the airwaves and public schools' regulation of free speech in classrooms.
It's delusional to think that the U.S. has unrestricted free speech, or to think that "free" implies completely "unconstrained".
>Free Speech doesn't mean having the right to say bad things about the government. It means having the right to say anything you want.
This is a strawman. No EU country restricts free speech to speech criticizing the government.
