A child does not just get up and say they are a another gender. They have to be groomed to believe what they are saying.

There is no known Gay gene.
Science hurts
It helps to read past the headline sometimes.
The researchers could not find any one gene linked with same-sex sexual behavior. Five genetic variants did appear significantly linked to sexual orientation, and thousands more also seemed involved to a lesser extent.
In the end, the scientists could not find any genetic patterns that could be used, in any way, to identify a person's sexual orientation. Instead, the predisposition to same-sex sexual behavior appeared influenced by a complex mix of genetic and environmental influences. That's also the case for many other human traits, such as height.
"It's effectively impossible to predict an individual's sexual behavior from their genome," study co-author Ben Neale, a statistical geneticist at the Broad Institute of MIT and Harvard, told Live Science.
However, the finding that there's no single gay gene does not mean that sexual orientation is not genetic or biological, and is therefore a lifestyle choice.
"This is wrong," study co-author Brendan Zietsch, a geneticist at the University of Queensland in Australia, told Live Science. "We find that there are many, many genes that predispose one to same-sex sexual behavior. Each of them individually has a very small effect, but together they have a substantial effect.
"Another possible misinterpretation is to think that if same-sex preference is genetically influenced, it must therefore be totally genetically determined," Zietsch added. "That is not true. Genetically identical individuals — twins — often have different sexual orientations. We know there are non-genetic influences as well, but we don't understand these well, and our study does not say anything about them."
However, some of the genetic variants identified in the massive study "could hint at some biological pathways that may be involved in same-sex sexual behavior," Ganna said. "So one variant, for instance, was located in a stretch of DNA that houses several genes related to the sense of smell. So, we know that smell has a strong tie to sexual attraction, but its links to sexual behaviors are not clear."
In addition, genes seemed to have greater influence on same-sex sexual behavior in men than in women, Ganna said.
The researchers suggested that genes may play a different role in same-sex behavior in males versus females because of biological factors, such as levels of testosterone and estrogen. Other factors, such as gendered social norms regarding the number of sexual partners females should have, could make women less comfortable accurately reporting their sexual behavior. That, in turn, could skew the results.
