Article is very homophobic. And they are quoting only research about MtF transgenders, but interviewing FtM instead. Research had 232 MtF transgenders, all from one same surgeon, one same city and group. And research is from 2005 year, about 1990-2005 years, so before all this transgender boom, when most transitioners were homosexual men. There few studies, but only one of them is actual research (from 2005 year), other ones seems to be political statements without much evidence or research done.

And study is weird, because "85% of participants experienced orgasm at least occasionally after SRS and 55% ejaculated with orgasm."

How they can ejaculate, if they had SRS? Study also said that many became asexual, so your idea about "social acceptable" seems to be true as well.

More frequent autogynephilic arousal after SRS was correlated with more frequent masturbation, a larger number of sexual partners, and more frequent partnered sexual activity

Plus study is mostly taking to account AGP transwomen, so nothing weird in them "changing" sexuality. Some of them seems were "virgins" before, so only after transition started dating and having sex - so most likely they were gay or bisexual men with internalized homophobia. I know at least one such gay man, who was saying they love women, but never dating one or liking any stars, they only liked male stars "for their actor talent", but after transition they "started dating men, they were straight before and they are straight now again".

Quoting the article (not study):

In tested transwomen [...] where 43% reported significant shifts in their sexual orientation (of 2+ points along the 7-point Kinsey scale).

+2 points on Kinsey scale is not significant, and it means that they were bisexual to begin with. So going from "Liking women a lot and liking men a bit" to "Liking women normally, and liking men a bit more" is not changing their sexuality at all.

it is undoubtedly fluid to some extent, so shifts in attraction could be no different from those that happen to many cisgender folks as well. Research with cisgender populations finds that almost 20% of young adult women and 5% of men report changes in their attractions over a 5-year period.

So "cis" gays and lesbians, or "cis" straight - 20% of them are becoming bisexual, and every 5 years their sexuality shifts a bit! Why no one is noticing it, then?

Imagine you’re in a female body and you identify on the masculine spectrum. You don’t want to be sexual with men, because those men would treat you as a female-bodied person, and that kind of sexual interaction is not of interest to you. So even if you did have attractions for men, you might not engage with men or even indulge in fantasies about men until you can be witnessed as and interacted with in your affirmed gender.

I have no words here.

Please. I don't even know how to respond to something this nonsensical. So basically, this supposed scientist's answer is, "I didn't let myself be attracted to men because I understand that men hurt women, so I have to be a man in order to safely be attracted to men." These poor young women. Instead of teaching young men to treat them right, we're teaching the women and girls that they can just become men and not have to deal with misogyny anymore. Because not wanting to be treated like a sex object means they're actually men.

I've noticed it is a lot with young lesbians, most of them seems to be non-binary or transmen. In videos someone posted here, from young detransitioners - all of them were lesbian tomboy girls, who were bullied for not looking feminine enough or for liking boys, but after transition they were praised and not bullied anymore. Tavistock own data from Keira Bell case showed that 2/3 of transmen (women) transitioned with reasoning of being tomboys or liking girls, I believe 1/3 were lesbians there. This trans movement is very toxic towards young GNC kids and towards LGB youth.
