Intersex individuals (i.e.: individuals with no clear classification of male/female) usually follow in the sexual orientation consistent with their gender identity. This demonstrates that sexual orientation is born out of psychological gender, rather than one’s biological gender.

This is horseshit. 9 times out of 10 intersex people DO have a clear classification of male/female. Klinefelter Syndrome (XXY Male) is one of the most common intersex conditions and NO ONE considers them "third sex" or female.

Intersex people are also far less likely to have a "gender identity" because we don't have the privilege of needing to make up fake "oppression." I am not male because I have a "male gender identity", I am male because I have a clearly developed penis.

That their homosexuality was related to their gender dissatisfaction is supported by the fact that designation of intersex infants as male or female has been shown to work best when the least genital reconstructive surgery is needed; the more masculine the genitalia appears already, the greater the success and satisfaction there will be with a male gender identity, and vice versa with a female gender identity. This is pointed out by Wisnieweski and Migeon when they explain that for patients with congenital micropenis, male sex of rearing was concluded optimal because genital reconstructive surgery is not required with this choice.12 As would be expected, genital surgery plays a large part in undermining the assigned gender of the child, by making them believe that their gender grouping is forced or artificial, thus making them more prone to self-identify with the gender opposite to their rearing. This is supported additionally by the recent work of Reiner and Gearhart13 who demonstrated that genetic males with Cloacal Exstrophy – a condition that leads to severe pelvic malformation and requires extensive surgery – have higher rates of gender dissatisfaction.

Oh look this article is literally advocating for cosmetic, abusive surgery on children. Intersex people don't experience "gender dissatisfaction" because we need invasive and botched genital surgeries, we experience it BECAUSE our society is so hung up on fake bullshit like gender roles and "gender identity" that we feel like, and are treated as, less than human because a lot of us have androgynous traits and thus don't "fit."
