My sense is that we may not need the language of innateness or genetics to understand that we are all ethically bound to recognize another person's declared or enacted sense of sex and/or gender. We do not have to agree upon the "origins" of that sense of self to agree that it is ethically obligatory to support and recognize sexed and gendered modes of being that are crucial to a person's well-being.
Judith ButlerI never did like the assertion of the "innate" inferiority or women or Blacks, and I understood that when people tried to talk that way, they were trying to "fix" a social reality into a natural necessity. And yet, sometimes we do need a language that refers to a basic, fundamental, enduring, and necessary dimension of who we are, and the sense of sexed embodiment can be precisely that.
Judith ButlerNot all bodies are born in male or female. There is a continuum of bodies and it seems to me that trying to persuade medical and psychiatrist establishments to deal with the intersex involves critique of the binary gender system. Similarly there continues to be extreme, sometimes very extreme violence against transgender people.
