What is a key principle regarding racial equality that members vow to uphold?

The key principle regarding racial equality that members of Delta Sigma Theta vow to uphold is the commitment to belittle no race. This principle underscores the organization's dedication to fostering respect and equality among all racial and ethnic groups. It reflects a stance against discrimination and promotes the idea of valuing each race equally, which is essential in the fight for social justice. Members are encouraged to actively challenge racist attitudes and behaviors and to advocate for unity and understanding among diverse communities. This principle aligns with the organization's mission to combat racial inequality and promote positive relationships among all people.

The other options do not align with the core values of Delta Sigma Theta; being indifferent to racism is counterproductive to the goal of combating discrimination, and promoting segregation directly opposes the principle of racial equality. Accepting all races, while positive, does not explicitly emphasize the importance of respect and acknowledgment of each race, which is central to the organization’s values.
