  This is not to suggest that such politics are uniform. For example, while Feinberg tends to emphasize the historical persistence of transgender people as a kind of people or oppressed group, Bornstein tends to emphasize the constructed (and oppressive) nature of gender categories as a whole, the desirability of viewing gender as fashion, and the importance of moving toward a more consensual gender system. Notably, Bornstein draws on the ethnomethodological work of Garfinkel (1967) and Kessler and McKenna (1977). The work of Kessler and McKenna is especially remarkable for its early broad use of ‘gender’ to apply even to biological sex in order to indicate the implication of sex within cultural interpretation and practice. Ethnomethodology is a sociological analysis of how individuals construct their common-sense knowledge of the world in social contexts. Bornstein draws principally on Garfinkel's notion of the natural attitude about sex. This attitude, for Garfinkel, constitutes the everyday “common-sense” about sex. It is held by those he dubbed “normals” for whom the categories male and female are exclusive, exhaustive, invariant, and applied on the basis of genitalia. Notably, part of the natural attitude involves dismissing counter-examples (e.g., intersexual individuals who show that the neat categorization of humans into two discrete categories is bogus) as abnormal and aberrant.
