What does it mean when it is said that people can vote regardless of their race or sex?

When it is stated that people can vote regardless of their race or sex, it emphasizes the principle of non-discrimination in voting. This means that all individuals, irrespective of their racial background or gender, have the right to participate in elections. This practice aligns with foundational democratic values that advocate for equal rights and representation. It highlights the importance of inclusivity in the electoral process, ensuring that everyone is granted the same opportunity to influence governance and policy, which is crucial for a functional democracy.

While other options touch on voting concepts, they do not capture the essence of equality and non-discrimination specific to race and gender. For instance, the term "universal" might suggest that voting is accessible to everyone, but it does not highlight the critical element of equality regarding personal identities. "Required" refers to the obligation to vote, which is a separate idea related to civic duty rather than the freedom to vote without discrimination. "Unrestricted" implies there are no limits on voting, but it lacks the specific focus on the absence of discrimination based on race and sex. Therefore, the notion of non-discrimination provides the most accurate understanding of the voting rights context indicated in the question.
