I can only give the definition that works for me. The clearest is that gender queer is not fitting into even the broadest definition of the gender binary of male/female as the only choices. For me personally it means that I am currently male bodied but my sense of self is far more female but there are aspects of me that are still quite male and others that are gender neutral. My sense of gender is not fixed and though I would love to use hormones to alter my body my sense of my gender does not depend on my physical appearance. For me gender identity is not a point on a line but a probability cloud like a electron.
Does thus definition help or is it too ambiguous
