What constitutional protection does the ordinance affecting Keller’s actions violate, if at all?

The ordinance affecting Keller's actions primarily infringes upon the right to free assembly. In this context, the right to free assembly protects individuals' ability to gather peacefully for demonstrations, protests, or other forms of collective expression. If an ordinance is imposed that unlawfully restricts the manner or extent to which people can gather, it can be viewed as a violation of this constitutional right.

The First Amendment guarantees American citizens the right to assemble peacefully, and any ordinance that excessively limits gatherings for political, social, or private purposes can be challenged on constitutional grounds. The fundamental principle behind this right is to ensure that individuals may come together to express their viewpoints, advocate for causes, and collectively participate in civic engagement without unreasonable interference from the government.

Understanding that the other rights listed, including the right to bear arms, the right to privacy, and the right to vote, pertain to different aspects of individual freedoms, it's clear that the specific context involving Keller directly ties to the protection of free assembly and the associated rights of individuals to gather and express their beliefs collectively.
