Erin Lee

Erin Lee is a Colorado parental-rights advocate and the executive director of Protect Kids Colorado. She is the designated proponent, alongside Republican strategist Michele Austin, of three 2026 state ballot measures: Proposition 133, which would mandate life in prison for child sex trafficking; Proposition 134, which would require school sports participation to be based on biological sex; and Proposition 135, which would prohibit gender-affirming surgeries for minors.

Lee's political advocacy began following a 2021 incident in which her middle-school daughter attended an after-school art club that functioned as a Gender and Sexuality Alliance meeting. Lee stated that school staff introduced her daughter to gender identity concepts and encouraged her to keep the discussions secret from her parents. In response, Lee sued the Poudre School District, arguing the district violated her constitutionally protected parental rights. The lawsuit, supported by the America First Policy Institute, was ultimately denied review by the U.S. Supreme Court in 2025.

In addition to leading Protect Kids Colorado, Lee is the founder of the advocacy group Stop Gender Ideology. She has frequently testified at the Colorado State Capitol against legislation expanding access to gender-affirming care and has spoken nationally on parental rights. She also produced "Art Club," a documentary detailing her experience with the school district.
