The international day against homophobia aims to coordinate international events to call respect for lesbians and gays world-wide. Unlike the LGBT Pride Day, which is meant to emphasise proudness of one's sexuality and refusal to be ashamed of it, IDAHO is held to highlight: May 17 was chosen as the day of the event because homosexuality was removed from the International Classification of Diseases of the World Health Organization (WHO) on May 17 1990.
