What characterizes a public forum?

A public forum is characterized by its traditional use as a space for public discourse, allowing individuals to engage in expression, assembly, and communication. This concept is rooted in constitutional law, particularly in the First Amendment, which protects the right to free speech and assembly in areas where these activities have been historically permitted.

Public forums can include parks, streets, and other public places where people gather to express their views or participate in political discussions. The designation of these areas as public forums reflects their importance in democratic society, serving as venues where diverse voices can be heard and where civic engagement can flourish.

The other options do not align with this definition: a space designated for private meetings contradicts the open nature of public discourse, a venue restricted to government use does not support public expression or participation, and areas with signage prohibiting gatherings would inherently limit the very freedoms that a public forum is meant to protect.
