Carter suggests that there are too many rules of speech that do not make the environment open to ideas. When institutions put up strict rules to prevent conflicts, people are reluctant to talk about important issues. This kind of fear prevents education from doing its job. By limiting restrictions instead of adding them, colleges can keep open a place for genuine intellectual discussion.

The comparison of McCarthyism suggests how fear instead of reason is used to make people think alike on campus. Under McCarthy, people were blacklisted and excluded based on their political beliefs, generally with little proof. Likewise, the author says the present campus climates create an atmosphere where students and professors fear to have differing opinions. This fear-based culture is, in a sense, even more restrictive than what the government can do, as it prevents honest discussion from occurring within rather than through external legal regulations.

There is a vital distinction between making a case for a point and closing down opposing viewpoints. Hence, students and teachers are intimidated into an agreement rather than challenged to make their case. By protecting the right to disagree, campuses preserve the principles of free inquiry and intellectual diversity that are essential to a healthy academic community.

Carter claims that this inquisitiveness must be applied even to opinions that are deemed objectionable or offensive. Rather than just rejecting or "cancelling" those who hold controversial beliefs, an intellectual environment strives to understand their reasoning. This does not mean one supports harmful ideologies but rather seeks to engage with them critically to challenge, modify, or strengthen one's opinion.
