The only valid censorship of ideas is the right of people not to listen.

Tommy Smothers (1937–2023), half of the comedy duo The Smothers Brothers, became a prominent public symbol of clashes over broadcast standards and political speech in the late 1960s. Their CBS variety program, “The Smothers Brothers Comedy Hour” (1967–1969), mixed music and satire with pointed commentary on the Vietnam War, civil rights, and generational conflict. The show repeatedly drew network objections and edits, and it was ultimately canceled amid disputes over “taste” and “controversy.” The remark about “the only valid censorship” reflects that era’s debates: whether institutions should suppress ideas deemed offensive, or whether audiences should simply refuse to watch, listen, or attend.

Smothers frames censorship as a matter of individual choice rather than institutional control. The “right … not to listen” treats exposure to ideas as voluntary: people can withdraw attention, change the channel, or walk away, but they should not prevent others from hearing. The line defends a robust marketplace of expression while acknowledging that audiences are not obligated to engage with every viewpoint. It also implicitly criticizes gatekeeping by networks, governments, or moral authorities who claim to protect the public by restricting speech. In this view, the ethical response to objectionable ideas is refusal and rebuttal, not suppression.
