The legal system can force open doors, and sometimes-even knock down walls, but it cannot build bridges. That job belongs to you and me. The country … - Thurgood Marshall

The central problem with Chicago's ordinance is that it describes permissible picketing in terms of its subject matter. Peaceful picketing on the subject of a school's labor-management dispute is permitted, but all other peaceful picketing is prohibited. The operative distinction is the message on a picket sign. But, above all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content. [Citations.] To permit the continued building of our politics and culture, and to assure self-fulfillment for each individual, our people are guaranteed the right to express any thought, free from government censorship. The essence of this forbidden censorship is content control. Any restriction on expressive activity because of its content would completely undercut the '"profound national commitment to the principle that debate on public issues should be uninhibited, robust, and wide-open." New York Times Co. v. Sullivan, supra, at 376 U. S. 270.

The experience of Negroes in America has been different in kind, not just in degree, from that of other ethnic groups. It is not merely the history of slavery alone, but also that a whole people were marked as inferior by the law. And that mark has endured.

I do not believe that the meaning of the Constitution was forever “fixed” at the Philadelphia Convention. Nor do I find the wisdom, foresight, and sense of justice exhibited by the Framers particularly profound. To the contrary, the government they devised was defective from the start, requiring several amendments, a civil war, and momentous social transformation to attain the system of constitutional government, and its respect for the individual freedoms and human rights, we hold as fundamental today. When contemporary Americans cite “The Constitution,” they invoke a concept that is vastly different from what the Framers barely began to construct two centuries ago.
