passage: The Supreme Court has held that ''advocacy of the use of force'' is unprotected when it is ''directed to inciting or producing imminent lawless action'' and is ''likely to incite or produce such action''. In Brandenburg v. Ohio (1969), the Supreme Court unanimously reversed the conviction of a Ku Klux Klan group for ''advocating ... violence ... as a means of accomplishing political reform'' because their statements at a rally did not express an immediate, or imminent intent to do violence. This rule amended a previous decision of the Court, in Schenck v. United States (1919), which simply decided that a ''clear and present danger'' could justify a congressional rule limiting speech. The primary distinction is that the latter test does not criminalize ''mere advocacy''.
question: is there a limit on freedom of speech?
Yes
