Queermisia can be defined as an aversion, hatred or mistrust of people who are, or appear to be, any sexual identity other than heterosexual. In this context, queer is used as an umbrella term to include anyone who is homosexual - gay or lesbian - as well as including people who are bisexual, pansexual, omnisexual, and any other mspec (multi-sexual spectrum) identity, and those who are demisexual, asexual, greysexual, etc. Using this term is not meant to diminish the real harm created by what we traditionally refer to as homophobia, but to be inclusive of all non-heterosexual people.
A Note on the Use of the Term Queer: Queer is often used to include expansive understadings of both sexuality and gender. Despite its history as a pejorative term, many have reclaimed this term as an expression of empowerment. While some embrace this term, others still find the term uncomfortable or offensive. Using the term queer in conversation should be used in proper context and never used for someone without their own consent.
