Well, universities across the United States, hospital administrators and violent protesters have made it hard, sometimes impossible, for dissident students, those who disagree with the prevailing views, to say what they think in public.
If state legislatures adopt such legislation, their state colleges will become true "free speech zones" - "safe spaces" for the free exchange of ideas.
During a Q&A session after his speech, Sessions was asked about the ongoing controversy over NFL players kneeling during the national anthem, which has sparked a series of scathing tweets from Sessions' boss, President Donald Trump. You have First Amendment rights in this country to speak and sometimes those rights can be impacted.
He argued the players were, in effect, "denigrating" symbols of the USA, and noted that while players wouldn't be subject to prosecution, they could expect condemnation for taking "provocative" actions.
Meanwhile, Sessions maintained freedom of thought and speech are under attack on college campuses.
"These are just three examples of governmental action antithetical to freedom of speech and association for which Attorney General Sessions is either closely affiliated or directly responsible", the professors wrote. Violent protests or the fear of such have led to the cancellation several planned speeches by conservatives at the University of California, Berkeley.
Trump had suggested in a speech last Friday that football teams should fire players who protest by kneeling for the anthem. He also expressed his concerns over the widespread assault upon this most sacred of rights, fueled on many college campuses around the country.
The Statesman has reached out to Boise State University officials for comment.
He criticized the universities for deciding "what is offensive and what is unacceptable" and for disinviting controversial speakers. He plans to highlight what he believes is the goal of the college education: "the search for truth, not the imposition of truth by a government censor". They will say that some speech is hurtful - even hateful. "Our colleague had every right to invite him to speak".
Inside the hall where Sessions spoke, a line of attendees sitting near the back stood up as the attorney general concluded his address.
McDonough Hall. "We're encouraging protesters to wear tape over their mouth", he says.
Sessions spoke specifically about a public college in Battle Creek, Michigan, where he said a state official had students jailed for handing out copies of the United States Constitution past year.
"We pay a ton of tuition", she said.
Lauren Phillips, a second-year law student, challenged Sessions on the apparent hypocrisy. Weinberg said that the event, which was organized by The Center for the Constitution, "was only open to invited students from across the Law Center who have in the past signed up to attend at least one event convened by the Center".
Sessions' speech, according to the school's website, was organized by its Center for the Constitution, led by high-profile professor Randy Barnett, who is known for his libertarian positions.
He derided student codes of conduct related to speech that he said "substantially infringe on constitutionally protected speech". Maybe they haven't been taught properly in the universities and colleges about what this means and why, historically, nations are important.
