In spring 2011, Hida was voted Chairperson of Organisation Intersex International, upon founder Curtis Hinkle's retirement. In the fall of 2011, they founded the Intersex Campaign for Equality, to work for equality and human rights for intersex Americans. Their first action, in December 2011, was contacting former Secretary of State Hillary Clinton to request the inclusion of intersex people in human rights protocols and protections. In early 2012, they received a response from the U.S. Department of State in early 2012 affirming the importance of including the intersex community in human rights work.
In 2012, they spearheaded the first unified, global call for human rights by and for intersex people, in a letter signed by thirty leading intersex advocacy organizations, to the Office of the United Nations High Commissioner for Human Rights. In 2013, Hida served as one of three intersex co-organizers of the Third International Intersex Forum that took place in November 2013, in Malta, which led to the creation of the Malta Declaration, the most widely agreed upon statement of human rights demands by the international intersex advocacy community. On Human Rights Day, on Dec 10th, 2013, Hida became the first openly intersex person to speak at the U.N., by invitation, at the event "Sport Comes Out Against Homophobia", along with fellow "out" pioneers, tennis legend Martina Navratilova, and NBA player Jason Collins. In 2014, they advocated against the IOC and IAAF's regulations for women with hyperandrogenism on a panel on the Al Jazeera television show The Stream. They also wrote about the interphobia and common misunderstandings around naturally occurring testosterone which drives sporting regulations for intersex women, in The Advocate.
In September 2015, the UN's Free & Equal Campaign for Equality produced a video of Hida in conjunction with the release of their groundbreaking resource the Intersex Fact Sheet, and in 2016 they were one of the "Intersex Voices" featured in the Free and Equal Campaign for Equality's Intersex Awareness Campaign. In 2016, Hida became a board member of Genital Autonomy America (GA America), an advocacy organization working with groups worldwide who are seeking to end non-therapeutic genital cutting of all female, male, and intersex infants and children.
