May 17 is International Day Against Homophobia, Biphobia, and Transphobia (IDAHOBIT Day)

What is IDAHOBIT? (from It Gets Better, Canada)
This day was created to mark the World Health Organization’s (WHO) important step to declassify homosexuality as a mental disorder, on May 17th, 1990.
Every year, advocates around the world call on local authorities, decision-makers, and the public to recognize and support the issues those with diverse sexual identities, gender expressions, and sex characteristics currently face.
Representation is ever-evolving
Originally called “International Day Against Homophobia” to reflect the WHO’s decision on homosexuality, the name has rightfully expanded—to reflect other identities.
First in 2009, to include transphobia and bring attention to the specific experiences at the intersection of sexual orientation and gender expression. And again in 2015, to include biphobia and acknowledge the issues faced by those who identify as bisexual.
