Are you born gay?

There was a study done on the chemical balances in the brains of 90 individuals. Some were homosexual, some were heterosexual and some were bisexual. It was determined that the chemical balances in a gay male’s brain were very similar to a straight females brain, and vice versa with women. Depending on which gender the bisexual was attracted to more, determined what his brain’s chemicals were more similar to. When someone is maturing through their teenage years, chemicals in their brain get distorted and for a period of time they find the same sex attractive which is why many people believe it’s a phase or a passing “fad.”
These chemicals balances are caused by genes. Now most people say, “Well there’s no gay gene, so that’s not possible.” According to science, it is a not a choice. Scientists discovered that women tend to have more children when they inherit the same genetic factors which are linked to homosexuality. This fertility boost more than compensates for the lack of offspring fathered by gay men, and continues the “gay” genetic factors in circulation. All people have three clustered chromosomes: 7, 8, and 10, which determine the sexual orientation. Being homosexual is inherited in the genes, and is neither a disease nor a sickness.
“Genetic investigations provide strong evidence for a heritable component to male and female sexual orientation,” Rahman Q et. al.; School of Psychology, University of East London
“The survival of a human predisposition for homosexuality can be explained by sexual orientation being a polygenetic trait that is influenced by a number of genes,” Miller EM.; University of New Orleans.
We only know of 5% of what the human genome does. 95% of the human genome is labeled as Junk DNA ( http://en.wikipedia.org/wiki/Junk_DNA ). It’s also theorized that this Junk DNA has an impact on sexual orientation, as well as other things.
So, since we established scientific proof and evidence, why can homophobes say ? Oh that’s right, all they have is a bible that 2/3rd’s of the world’s population don’t even believe in …
So how do you guys feel about this ?
