On May 17th, 2015 gays and lesbians, bisexual and transgender people, their parents and children, friends and peers in many cities around the world let the colorful baloons fly in the sky as a symbolic move to combat homophobia and transphobia.

On this very day 25 years ago the World Health Organization after many years of research excluded homosexuality from the list of mental disorders.
