Trans people have the potential to transform the gender class system as we know it. Our existence challenges the conventional wisdom that the differences between men and women are primarily a product of biology. Trans people can wreak havoc on such taken-for-granted concepts as feminine and masculine, homosexual and heterosexual, because those words are rendered virtually meaningless when a person’s biological sex and lived sex are not the same. But because we are a threat to the categories that enable male and heterosexual privilege, the images and experiences of trans people are presented in the media in a way that reaffirms, rather than challenges, gender stereotypes.
