Historically used as a pejorative term, queer has largely been reclaimed as an umbrella term or self-identification by and for people with diverse sexual orientations and gender identities. It is a popular option for self-identification because its meaning is not fixed or specific, thus one is not required to fit one’s identity into a pre-determined box. Keep in mind that some people may still take offence to the term, however, so use it with caution. As always, ask people how they self-identify and use whatever term is preferred by the person in question.
