Queerphobia is a hatred or fear of people who identify as queer. The term is a portmanteau queer, an umbrella term for members of the LGBTQ+ community, and phobia, a persistent and often illogical fear. The term has been in common usage since the late 1990s.
Queerphobic people may dislike or fear homosexual people, bisexual people, transsexual people, and others who classify themselves as queer.
Queerphobia was originally written queer-phobia, but is more commonly accepted as one word today.
