A question on Philosophy.SE required transgenderism to be defined in order to determine whether the notion conflicted with traditionally defined feminism.
In my answer, I quoted an online dictionary's definition of the concept and phrase gender dysphoria, defining it as:
The condition of feeling one's emotional and psychological identity as male or female to be opposite to one's biological sex.
I noted that if the referenced “feeling” denotes a discrepancy between one’s behavioral predispositions and the behavioral dispositions deemed appropriate by society and culture to one’s biological gender (the supposedly socially constructed gender role of one’s biological gender), then there would arguably seem to be some conflict between transgenderism and feminism as defined by the interlocutor (arguably the traditional definition).
This answer was met with the following retort:
Your answer adheres to the anachronistic gender binary. There are plenty of gender non-binary trans folk. The dichotomy between "male" and "female" as opposed is false.
My response was that although I understood the notion of non-binary gender roles, I could not quite (hermaphrodites aside) make sense of non-binary gender, since that term is reputed to be synonymous with the term sex, generally defined in terms of reproductive functions.
On a hunch, I went to the Urban Dictionary and looked up the definition of androgyny and found it defined in terms of gender roles, not gender:
Androgyne: An individual who feels they do not properly fit into the gender roles ascribed by society to males and females. Often feels as though their gender is beyond the understanding of these limiting societal factors and seeks to free themselves from that which limits them by dress in androgynous clothing and attempting to appear on the outside as they feel on the inside.
I find myself embroiled in nascent ontological types, metaphysical categories; which suggests that I am at the cutting edge of language, where terms are in the process of being invented, usages prescribed — so prescriptive, rather than descriptive, notions tend to dominate (since very little empirical evidence exists) as new concept terms are being assigned extensions and connotations.
My specific questions are:
Is sex a synonym of gender?
If these terms are deemed to be distinct, what is the difference between the terms gender and gender role?
Is there a difference in definition or usage between an androgyne and gender–non-binary trans-folk — and if so, what is it?
Any usage recommendations or definitions deemed relevant to this family of terms would be appreciated.
