I heard one of the authors of this new study commenting on how he was a gay man, and the purpose of his research was to show a genetic basis for homosexuality, in order to make it equal to race. His goal was to make it impossible to disagree with homosexual behavior, because homosexual behavior would be seen as natural and normal. Let’s see if his new study helps him out.
The blog of the peer-reviewed journal PLOS One reported on the new study, which was published in the prestigious journal Science.
The once-prevailing concept of a “gay gene” dictating sexual orientation has been put to rest in a powerhouse study published today in Science. The work brilliantly illustrates the very nature of science: evolving with the input of new data, especially the large-scale contributions of bioinformatics and crowd-sourcing.
“We formed a large international consortium and collected data for more than 500,000 people, comparing DNA and self-reported sexual behavior. This is approximately 100 times bigger than any previous study on this topic,” said lead author Andrea Ganna, of the Institute of Molecular Medicine in Finland and an instructor at Massachusetts General Hospital and Harvard Medical School, opening a news conference earlier this week.
[…]The investigation estimates a genetic contribution to same-sex sexual behavior as under 1 percent, thanks to analysis of a trove of data from the UK Biobank and the consumer genetic testing company 23andme.
So, there you have it, there is no gay gene. But this is of course something we’ve known for decades, as all the previous studies had found the same thing.
The normal way that people do these studies is to analyze identical twins, and see how often both identical twins are gay.
Eight major studies of identical twins in Australia, the U.S., and Scandinavia during the last two decades all arrive at the same conclusion: gays were not born that way.
“At best genetics is a minor factor,” says Dr. Neil Whitehead, PhD. Whitehead worked for the New Zealand government as a scientific researcher for 24 years, then spent four years working for the United Nations and International Atomic Energy Agency. Most recently, he serves as a consultant to Japanese universities about the effects of radiation exposure. His PhD is in biochemistry and statistics.
Identical twins have the same genes or DNA. They are nurtured in equal prenatal conditions. If homosexuality is caused by genetics or prenatal conditions and one twin is gay, the co-twin should also be gay.
“Because they have identical DNA, it ought to be 100%,” Dr. Whitehead notes. But the studies reveal something else. “If an identical twin has same-sex attraction the chances the co-twin has it are only about 11% for men and 14% for women.”
Because identical twins are always genetically identical, homosexuality cannot be genetically dictated. “No-one is born gay,” he notes. “The predominant things that create homosexuality in one identical twin and not in the other have to be post-birth factors.”
Dr. Whitehead believes same-sex attraction (SSA) is caused by “non-shared factors,” things happening to one twin but not the other, or a personal response to an event by one of the twins and not the other.
By the way, a previous study also found that transgender behavior was not genetic, but was clearly linked to environmental factors such as peer approval and social media.
Here is the report from Science Daily:
This month, a Brown University researcher published the first study to empirically describe teens and young adults who did not have symptoms of gender dysphoria during childhood but who were observed by their parents to rapidly develop gender dysphoria symptoms over days, weeks or months during or after puberty.
[…]The study was published on Aug. 16 in PLOS ONE.
Littman surveyed more than 250 parents of children who suddenly developed gender dysphoria symptoms during or after puberty.
[…]“Of the parents who provided information about their child’s friendship group, about a third responded that more than half of the kids in the friendship group became transgender-identified,” Littman said. “A group with 50 percent of its members becoming transgender-identified represents a rate that is more 70 times the expected prevalence for young adults.”
A previous study also found that children are more likely to be gay if they are raised by gay adults. It was reported in AOL News.
Walter Schumm knows what he’s about to do is unpopular: publish a study arguing that gay parents are more likely to raise gay children than straight parents. But the Kansas State University family studies professor has a detailed analysis that past almost aggressively ideological researchers never had.
[…]His study on sexual orientation, out next month, says that gay and lesbian parents are far more likely to have children who become gay. “I’m trying to prove that it’s not 100 percent genetic,” Schumm tells AOL News.
His study is a meta-analysis of existing work. First, Schumm extrapolated data from 10 books on gay parenting… [and] skewed his data so that only self-identified gay and lesbian children would be labeled as such.
[…]Schumm concluded that children of lesbian parents identified themselves as gay 31 percent of the time; children of gay men had gay children 19 percent of the time, and children of a lesbian mother and gay father had at least one gay child 25 percent of the time.
[…]Finally, Schumm looked at the existing academic studies… In all there are 26 such studies. Schumm ran the numbers from them and concluded that, surprisingly, 20 percent of the kids of gay parents were gay themselves. When children only 17 or older were included in the analysis, 28 percent were gay.
It’s very important for people to understand that there is a trend in society to make every behavior traditionally seen as sinful into something caused by genetics. The twin goals of this effort are to insulate the behaviors from criticism, and to minimize evaluation of the effects of these behaviors on society as a whole. The genetic argument was used extensively to normalize same-sex marriage and transgenderism. I have seen the genetic argument used to defend other behaviors like pedophilia and incest. But the scientific research does nothing to support any of these arguments. What’s amazing is how a majority of people in the United States have such false beliefs about the scientific research. They vastly overestimate the number of gay people, and also the influence of genetics.

The “gay gene” construct was another softening of opposition to homosexuality. It was a tool in the way that tolerance, acceptance, celebration and now participation all have been used to make the gay lifestyle broadly acceptable — and thus further destroy the nuclear family. And it worked. But none of it was ever true. Thanks, WK.

Results of twin studies, and mere anecdotal observations of them, would seem to put to bed any idea of a determinative “gay gene” (“determinative,” like eye color). It’s a good inclusion in your article here. What’s missing (or not explicitly argued) is the point that, even if it were the case that there was a gay gene, it does not then follow that a gay lifestyle is a healthy, morally, and socially benign thing to be practiced and celebrated. There are many behaviors and sexual predilections that are still largely disaffirmed by society, which can likewise be argued to be genetic (as you point out), and we certainly don’t “celebrate” truly congenital, physical conditions. Arguing for the social acceptance of LGBTQ+ issues has to be conducted on its own terms, and not just because it’s “natural” somehow. Animals eating their own, or competitor’s, offspring is also “natural,” after all.

In my experience, when you get to the bottom of it, the arguments for adding new things to alphabet sexuality is this: “Some people have the desire to do X. It doesn’t really bother me. Therefore X is okay and it shouldn’t bother you either.”
