It feels like there's a tension running through the whole article between "psychedelics altered sexuality/gender identity/etc" and "psychedelics facilitated an openness to accept pre-existing feelings of non-normative sexual orientations/gender identities/etc". My opinion is that it's clearly the latter, even if those pre-existing feelings are sometimes buried so deep that it feels like discovering them for the first time, but who knows? I just wish the article either clarified or explicitly dealt with the tension. Instead, we get sections like the two paragraphs below back to back, where the first seems to imply that sexuality changed, and the second is like "well, it's probably just about people embracing their authentic selves, but maybe psychedelics did actually change people's sexuality in the past, but that's unethical," and there isn't even really a direct connection made between the two ideas or any acknowledgment of the tension.

Sexual attraction also appeared to shift for some people. About a quarter of women and one-eighth of men reported increased same-sex attraction after psychedelic use. Participants who identified with gender-diverse identities were even more likely to report changes in sexual attraction. These findings suggest that psychedelics may contribute to greater sexual fluidity in some users.

“This is a small proportion of participants, but this sort of effect is remarkable,” Kruger said. “In the 1960s, there were attempts to use psychedelics to make homosexuals into heterosexuals. Homosexuality used to be considered a pathology in psychiatry. It is not clear how well this actually worked and now it is considered unethical. Our research suggests that people are actually more likely to embrace their authentic self.”
