Last year, an American research group asked people in 38 countries for their opinions about free speech.
What the researchers discovered may surprise you. They found that people in the United States are the most accepting of free speech, even when the comments are critical of their own religious beliefs.
The Pew Research Center completed the opinion survey. Its researchers said the findings are timely.
They noted that some college officials are debating whether to set up "safe spaces," or "trigger warnings," so students can avoid discussions they might finding troubling.
A safe place is a place where students can feel at ease discussing concerns without being judged or criticized. A trigger warning is when a teacher warns that a class discussion or reading might be troubling to some students.
There has been debate in recent weeks about athletes who refuse to stand for the U.S. national anthem to protest racial injustice. Some Americans say athletes should be free to express their concerns about racial injustice. But others say everyone should show respect for the country's national anthem.
The Pew Research Center said its 2015 survey found that 71 percent of Americans said "people can say what they want." Sixty-seven percent said that the media can report the news freely.
Pew used its findings to create measures of free expression for all 38 nations it surveyed.
It said the free expression index in the United States is 5.73. That was the highest among the 38 nations in the study.
Pew said the 2nd highest index was Poland, at 5.66, followed by Spain, Mexico, Venezuela and Canada. All these countries have a free expression index of 5.0 or higher, it said.
The lowest free expression indexes were in Senegal, at 2.06; Jordan, 2.52; Pakistan, 2.78; Burkina Faso, 2.94; and Vietnam, 2.96.
In the United States, Pew found that 40 percent of Millennials believe the government should protect minority groups against offensive statements. They said the government should take action to stop people from making statements that the minorities consider offensive.
For the study, Pew defined Millennials as people born after 1980.
The percentages of people who say the government should stop offensive statements is lower for older Americans, the group said.
In July, a Pew report found 59 percent of Americans agree that "too many people are easily offended these days over the language that others use." It found a lower percentage, 39 percent, agree that "people need to be more careful about the language they use to avoid offending people with different backgrounds."
A group called the Foundation for Individual Rights in Education opposes moves to limit free speech on college campuses. Nico Perrino speaks for the foundation.
"American citizens have a long tradition of meeting speech they find offensive with more speech, not censorship," he said.
But Perrino is troubled by efforts to limit free speech at some colleges.
"This is a concerning development," he said. Over the years, he noted, students have been among the strongest supporters of free speech.
But there is support for safe spaces and trigger warnings to protect students from material or opinions they might find troubling.
A University of Chicago student recently wrote an opinion piece for The New York Times newspaper.
The student, Sophie Downes, expressed opposition to the university's decision to stop trigger warnings and safe spaces. A professor who provides a trigger warning can help students get ready emotionally to deal with difficult subjects, she wrote.
Downes said the political debate in the United States lately "has become pretty ugly, so it's not surprising that students are looking for places to have civil discussions."
At some schools, supporters of trigger warnings say that a student who has been physically attacked might suffer emotional harm by a talk that includes violent language.
This year, the University of Chicago wrote a letter to its new students, saying it will not cancel speakers who might express opinions that some students might find troubling.
The letter said the university wants students "to speak, write, listen, challenge and learn without fear of censorship."
