Sentence:  Every other mode of social discourse is "other," whether it be termed "gay" (or the newly acceptable "queer"), "bisexual", or "asexual", or embodied in the concept of the "spinster", the "confirmed bachelor", the "old maid", or the "same-sex couple" who will never fit into the "<WSD>straight</WSD>" world, and doesn't or don't want to. The state of nonstraightness is essentially suspect; it is not seen as "right [or] correct." 
Meaning of the word marked with <WSD> tags:  Heterosexual.
