 Gay and lesbian theory was thus faced with three significant problems, all of which involved difficulties with the notion of ‘identity.’ Queer theory arose in large part as an attempt to overcome them. How queer theory does so can be seen by looking at the term ‘queer’ itself. In contrast to gay or lesbian, ‘queer,’ it is argued, does not refer to an essence, whether of a sexual nature or not. Instead it is purely relational, standing as an undefined term that gets its meaning precisely by being that which is outside of the norm, however that norm itself may be defined. As one of the most articulate queer theorists puts it: “Queer is … whatever is at odds with the normal, the legitimate, the dominant. There is nothing in particular to which it necessarily refers. It is an identity without an essence” (Halperin, 1995, 62, original emphasis). By lacking any essence, queer does not marginalize those whose sexuality is outside of any gay or lesbian norm, such as sado-masochists. Since specific conceptualizations of sexuality are avoided, and hence not put at the center of any definition of queer, it allows more freedom for self-identification for, say, black lesbians to identify as much or more with their race (or any other trait, such as involvement in an S &amp; M subculture) than with lesbianism. Finally, it incorporates the insights of poststructuralism about the difficulties in ascribing any essence or non-historical aspect to identity.
