PRINCETON, NJ, May 20, 2015 (LifeSiteNews.com) -- For the first time, a majority of Americans say that homosexuals are "born that way."
According to the latest Gallup poll, 51 percent of Americans say that people are born gay or lesbian, while only 30 percent say outside factors such as upbringing and environment determine sexual orientation.
Peter Sprigg of the Family Research Council says that these numerous, rigorous studies of identical twins have now made it impossible to argue that there is a "gay gene." If homosexuality were inborn and predetermined, then when one identical twin is homosexual, the other should be, as well.
Yet one study from Yale and Columbia Universities found homosexuality common to only 6.7 percent of male identical twins and 5.3 percent of female identical twins.
The low rate of common homosexuality in identical twins – around six percent – is easily explained by nurture, not nature.
Researchers Peter Bearman and Hannah Brueckner concluded that environment was the determining factor. They rejected outright that "genetic influence independent of social context" as the reason for homosexuality. "(O)ur results support the hypothesis that less gendered socialization in early childhood and preadolescence shapes subsequent same-sex romantic preferences."
"Less gendered socialization" means, a boy was without a positive father figure, or a girl was without a positive mother figure.
In light of the evidence, Sprigg said simply, "No one is born gay."
