||The relevant language from the majority opinion is the following:
"The Ohio Criminal Syndicalism Statute was enacted in 1919. From 1917 to 1920, identical or quite similar laws were adopted by 20 States and two territories. E. Dowell, A History of Criminal Syndicalism Legislation in the United States 21 (1939). In 1927, this Court sustained the constitutionality of California's Criminal Syndicalism Act, Cal. Penal Code 11400-11402, the text of which is quite similar to that of the laws of Ohio. Whitney v. California, 274 U.S. 357 (1927). The Court upheld the statute on the ground that, without more, "advocating" violent means to effect political and economic change involves such danger to the security of the State that the State may outlaw it. Cf. Fiske v. Kansas, 274 U.S. 380 (1927). But Whitney has been thoroughly discredited by later decisions. See Dennis v. United States, 341 U.S. 494 , at 507 (1951). These later decisions have fashioned the principle that the constitutional guarantees of free speech and free press do not permit a State to forbid or proscribe advocacy of the use of force or of law violation except where such advocacy is directed to inciting or producing imminent lawless action and is likely to incite or produce such action. [fn] As we [395 U.S. 444, 448] said in Noto v. United States, 367 U.S. 290, 297 -298 (1961), "the mere abstract teaching . . . of the moral propriety or even moral necessity for a resort to force and violence, is not the same as preparing a group for violent action and steeling it to such action." See also Herndon v. Lowry, 301 U.S. 242, 259 -261 (1937); Bond v. Floyd, 385 U.S. 116, 134 (1966). A statute which fails to draw this distinction impermissibly intrudes upon the freedoms guaranteed by the First and Fourteenth Amendments. It sweeps within its condemnation speech which our Constitution has immunized from governmental control. Cf. Yates v. United States, 354 U.S. 298 (1957); De Jonge v. Oregon, 299 U.S. 353 (1937); Stromberg v. California, 283 U.S. 359 (1931). See also United States v. Robel, 389 U.S. 258 (1967); Keyishian v. Board of Regents, 385 U.S. 589 (1967); Elfbrandt v. Russell, 384 U.S. 11 (1966); Aptheker v. Secretary of State, 378 U.S. 500 (1964); Baggett v. Bullitt, 377 U.S. 360 (1964)."
