Some states are now allowing a third option on driver licenses rather that just M/F

This is such a complex area of discussion. I don't believe that the article is saying that there is anything wrong with being very masculine or feminine. It seems to me that it is just explaining that many people don't fit into that category. We do seem to get defensive when sexuality and gender identity are discussed. We have a wide range of genders that people identify with. Could it be that there are so many shades of genders that we can't name them all? Included in these shades of gender are the firmly male and female people.

I think that the majority of our gender roles are guided by society. Especially ones like colors ( pink and blue) or strength. Passive? Aggressive? We are taught from the moment of birth what is the correct way to behave in respect to what genitals we have. Some people are somewhere in between.
The act of sex also seems to set our personalities. People are still debating if people are taught whom to be attracted to or if it is innate.
It would be nice to be able to discuss these things without all the guilt and shame that society seems to surround these topics.

Here is an EXCERPT of the articles listed above.

I've been uScholars who study the gender binary from an intersectional feminism and critical race theory[23] perspective agree that during the process of European colonization of the U.S., a binary system of gender was created and enforced as a means of protecting patriarchal norms and upholding European nationalism.[24] This idea of a gender as a binary is thought to be an oppressive means of reflecting differential power dynamics.[25] Studies of Two Spirit traditions have shown that various Native American nations understand gender and sexuality in a way that directly opposes Western norms.[26]

Gender binarism also poses limitations on the adequacy of medical care provided to gender nonconforming patients. There is a large gap in medical literature on nonbinary populations who have unique healthcare needs.[27]sing the word "they" for years. It feels very natural to me.

No disrespect for the androgynous, but there’s nothing wrong with being very masculine or very feminine. Those characteristics are not shallow social constructs IMO, but are deeply imbedded human qualities that evolved over millennia. Look out on a pasture. You can certainly tell the cows from the bulls, can’t you?
