Payne, like many ex-gay advocates, presents views of homosexuality that are distinctly Freudian. She presents a narrative of female homosexuality where the infant is attached to the mother, and then must go through a process of “emotional and physical separation.” When the attachment was not originally able to occur, the child seeks out attachments from others, in ways that could result in lesbianism.
In his essay “Female Sexuality,” Freud likewise argues that female development involves an initial attachment to one’s mother, which must eventually develop into a separation from the mother (Freud puts it in terms of the girl developing a “reproach” towards her mother) and affinity to the father. This shift corresponds to a focus on the proper “love-object” for her, the male.
Payne’s grounding in pseudo-Freudian theory can be further seen in her describing lesbian behavior as a “sexual neurosis” which can be “manifested in a hysterical personality.” These aren’t Biblical terms. As concepts, these don’t predate the modern era. They come largely from the work of Freud.
The lineage for Payne’s views on homosexuality isn’t the Bible. It’s Freud, the same guy who called religion a “universal obsessional neurosis.”
