Adjective. In a very basic sense, anyone who is not heterosexual and/or cisgender. In the past, queer was a negative or pejorative term for people who are gay, and thus it is sometimes disliked. But the term is increasingly being used to describe all identities and politics that go against normative beliefs. As such, the term is valued by many LGBTQ+ people for its defiance and by others who find it to be an appropriate term to describe their more fluid identities.
