Which of the following is a common limit on speech that the government can enforce?

The principle behind limiting speech that incites imminent lawless action is rooted in the need to maintain public order and safety. This particular restriction is firmly established within First Amendment jurisprudence. The Supreme Court case Brandenburg v. Ohio (1969) clarified that speech can be regulated if it is directed to inciting or producing imminent lawless action and is likely to produce such action.

This means that while individuals have broad rights to express their opinions, the government can intervene when speech poses a direct and immediate risk of resulting in illegal actions. This standard strikes a balance between the fundamental right to free speech and the need to protect society from potential harm. Other options, such as public opinion, personal beliefs, and political affiliation, do not constitute legal standards that allow government intervention in speech. They represent subjective concepts that are integral to individual identity and expression but do not inherently provide a basis for legal limitations on speech.
