24 CITIZENS UNITED v. FEDERAL ELECTION COMM’N Opinion of the Court here. Premised on mistrust of governmental power, the First Amendment stands against attempts to disfavor certain subjects or viewpoints. See, e.g., United States v. Playboy Entertainment Group, Inc., 529 U. S. 803, 813 (2000) (striking down content-based restriction). Prohibited, too, are restrictions distinguishing among different speakers, allowing speech by some but not others. See First Nat. Bank of Boston v. Bellotti, 435 U. S. 765, 784 (1978). As instruments to censor, these categories are interrelated: Speech restrictions based on the identity of the speaker are all too often simply a means to control content. Quite apart from the purpose or effect of regulating content, moreover, the Government may commit a consti tutional wrong when by law it identifies certain preferred speakers. By taking the right to speak from some and giving it to others, the Government deprives the disadvan taged person or class of the right to use speech to strive to establish worth, standing, and respect for the speaker’s voice. The Government may not by these means deprive the public of the right and privilege to determine for itself what speech and speakers are worthy of consideration. The First Amendment protects speech and speaker, and the ideas that flow from each. The Court has upheld a narrow class of speech restric tions that operate to the disadvantage of certain persons, but these rulings were based on an interest in allowing governmental entities to perform their functions. See, e.g., Bethel School Dist. No. 403 v. Fraser, 478 U. S. 675, 683 (1986) (protecting the “function of public school educa tion”); Jones v. North Carolina Prisoners’ Labor Union, Inc., 433 U. S. 119, 129 (1977) (furthering “the legitimate penological objectives of the corrections system” (internal quotation marks omitted)); Parker v. Levy, 417 U. S. 733, 759 (1974) (ensuring “the capacity of the Government to discharge its [military] responsibilities” (internal quota
