“It's not fair – It's not safe. Bigger, stronger biological males are invading girls' sports in Colorado, taking away our girls' dignity, safety, and opportunity. Our ballot measure ensures girls' sports are protected, requiring sports leagues and teams be specifically designated male, female, or co-ed. Because girls' sports in Colorado should be for girls. That's it.” - Protect Kids Colorado 

“Initiative #109 affirms the "unique and immutable biological differences" between men and women from birth and that those differences become more pronounced as children age and reach puberty. Initiative #109, therefore, requires all interscholastic and intermural athletic programs to be expressly designated based on biological sex as either for men, women, or coeducational (co-ed). School and athletic organization policies that undermine the biological reality of a person's body as male or female deny human dignity and are abusive to minors. Policies that allow biological men to participate in women's sports promote the unfair treatment of women and pose potentially dangerous and inappropriate situations for young women, including sharing bathrooms and locker rooms with biological men. Title IX of the Education Amendments of 1972 was a needed landmark to establish equal educational opportunities for women. Initiative #109 keeps in continuity with Title IX, is important for the equal dignity of men and women and addresses the unfair competition and potential safety concerns for minors when biological sex is disregarded.” - Colorado Catholic Conference   

“Questions about fairness and safety in competitive athletics are legitimate, but Initiative 109 imposes a one-size-fits-all rule based solely on biological sex, extending from collegiate athletics all the way to K–12 and intramural sports. It would exclude transgender girls and women from female teams regardless of age, sport, level of competition, or individual circumstances, while transgender boys and men could participate on male teams only when no corresponding female team is available. That rigid approach leaves schools and athletic governing bodies little ability to account for circumstances such as medical transition, hormone treatment, or the very different competitive considerations presented by different sports and ages. These complicated questions call for thoughtful, evidence-based policies rather than a sweeping statewide mandate.” - Eagle County Democrats
