Problem:Why might these words - homosexual and hetero sexual - be offensive to a person after they have surgically changed sexes?, Context: Some researchers, such as Bruce Bagemihl, have criticized the labels "heterosexual" and "homosexual" as confusing and degrading. Bagemihl writes, "...the point of reference for 'heterosexual' or 'homosexual' orientation in this nomenclature is solely the individual's genetic sex prior to reassignment (see for example, Blanchard et al. 1987, Coleman and Bockting, 1988, Blanchard, 1989). These labels thereby ignore the individual's personal sense of gender identity taking precedence over biological sex, rather than the other way around." Bagemihl goes on to take issue with the way this terminology makes it easy to claim transsexuals are really homosexual males seeking to escape from stigma.
Solution:
this nomenclature is solely the individual's genetic sex prior to reassignment
