What is "queer?"
Queer: An umbrella term that can refer to anyone who transgresses society's view of gender or sexuality. The definitional indeterminacy of the word Queer, its elasticity, is one of its constituent characteristics: "A zone of possibilities". It has gained some acceptance as an inclusive term, but one should be mindful of where they it, especially if they do not identify as queer.
The letters in LGBTQIAP (Lesbian, Gay, Bisexual, Transgender, Queer/Questioning, Intersex, Asexual, and Polyamorous) are not meant to be exhaustive, or to sort people into clearly defined categories. A person might just like to use these terms to describe themselves. They may use more than one or none of them. There are many variances; these identities are just part of who a person is.
