For much of the 20th century, young Americans were seen as free speech’s fiercest defenders. But now, young Americans are growing more skeptical of free speech.
According to a March 2025 report by The Future of Free Speech, a nonpartisan think tank where I am executive director, support among 18- to 34-year-olds for allowing controversial or offensive speech has dropped sharply in recent years.
In 2021, 71% of young Americans said people should be allowed to insult the U.S. flag, which is a key indicator of support for free speech, no matter how distasteful. By 2024, that number had fallen to just 43% – a 28-point drop. Support for pro‑LGBTQ+ speech declined by 20 percentage points, and tolerance for speech that offends religious beliefs fell by 14 points.
This drop contributed to the U.S. having the third-largest decline in free speech support among the 33 countries that The Future of Free Speech surveyed – behind only Japan and Israel.
Why has this support diminished so dramatically?
Shift from past generations
In the 1960s, college students led what was called the free speech movement, demanding the right to speak freely about political matters on campus, often clashing with older, more censorious generations.
Sociologist Jean Twenge has tracked changes in attitudes using data from the General Social Survey, a biennial survey conducted by the University of Chicago’s National Opinion Research Center.
Since the 1970s, this survey has asked Americans whether controversial figures – racists, communists and anti-religionists – should be allowed to speak. Support for such rights generally increased from the Greatest Generation, born between 1900-1924, to Gen X, born between 1965-1979.
But Gen Z, those born between 1995-2004, has reversed that trend. Despite the fact that the Cold War, which pitted the communist Soviet Union and its allies against the democratic West, ended more than three decades ago, even support for the free speech rights of communists has declined.
Political drift and cultural realignment
At the same time, some data suggests that young Americans may be drifting rightward politically.
A Harvard Institute of Politics poll in late 2024 found that men ages 18–24 now identify as slightly more conservative than those ages 25–29. Another Gallup survey showed that Gen Z teens are twice as likely as millennials to describe themselves as more conservative than their parents were at the same age.
This shift may help explain changes in speech attitudes.
Today’s young Americans may be less likely to instinctively defend speech aligned with liberal or progressive causes. For example, support among 18- to 29-year-olds for same-sex marriage, generally considered a liberal or progressive cause, fell from 79% in 2018 to 71% in 2022, according to Pew Research.
Attitudes toward hate speech
The Future of Free Speech study found that younger Americans are especially hesitant to defend speech that offends minority groups.
Only 47% of those ages 18 to 34 said such speech should be allowed, compared with 70% of those over 55.
Similarly, tolerance for religiously offensive speech was 57% among younger respondents, down from 71% in 2021.
This concern over harmful or bigoted speech is not new. A 2015 Pew survey found that 40% of millennials believed the government should be able to prevent offensive speech about minorities.
More recently, a 2024 report by the nonpartisan free speech advocacy group FIRE found that 70% of U.S. college students supported disinviting speakers perceived as bigoted. Over a quarter said violence could be acceptable to stop campus speech in some cases.
Broader implications
Why does this matter?
The First Amendment protects unpopular speech. It does not just shield offensive ideas, but it safeguards movements that once seemed fringe. Whether it’s civil rights, LGBTQ+ rights or anti-war protests, history shows that ideas seen as dangerous or radical in one era often become widely accepted in another.
Today’s younger Americans will soon shape policies in universities, media, government, tech and the public square. If a growing share believes speech should be regulated to prevent offense, that could signal a shift in how free speech is interpreted and enforced in American institutions.
To be sure, support for free speech in principle remains strong. The Future of Free Speech report found that 89% of Americans said people should be allowed to criticize government policy. But tolerance for more provocative or offensive speech appears to be eroding, especially among young people.
This raises questions about whether these changes reflect a life-stage effect − will today’s young people become more speech-tolerant as they age? Or are we seeing a deeper generational shift?
The data suggests Americans across all generations still value free speech. But for younger Americans, especially, that support seems increasingly conditional.

I don’t think that the older generation was so much more conservative, they were more concerned with manners. To blather out nasties, at the top of their lungs, would have been considered excessively rude. People did it, but it was not considered in good taste. People, in general, kept the offensive thoughts to themselves. Manners have all but disappeared. Being more restrictive in how others should think doesn’t fix much of anything.
Young people did not invent free speech, nor were they more of advocates protecting it. Some thought that joeshmo12345 calling a named person a thief or monster, and not making it clear it was simply their opinion, as free speech. It is not. It has legal consequences, and for a good reason.
I support disrespecting the flag, not because I like it, or want to, but because it is the oppressive countries that do not allow it. Oppression is not the American way, and not everyone is going to agree with me. That’s good. Oppression is the way of China, or North Korea. That we do not want.
I hope the younger generations consider, and understand, this.
