Identical Twin Studies Prove Homosexuality is Not Genetic
 
This should be a fun thread!

Quote:

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.

For example, one twin might have exposure to pornography or sexual abuse, but not the other. One twin may interpret and respond to their family or classroom environment differently than the other.

“These individual and idiosyncratic responses to random events and to common environmental factors predominate,” he says.

The first very large, reliable study of identical twins was conducted in Australia in 1991, followed by a large U.S. study about 1997. Then Australia and the U.S. conducted more twin studies in 2000, followed by several studies in Scandinavia, according to Dr. Whitehead.

“Twin registers are the foundation of modern twin studies. They are now very large, and exist in many countries. A gigantic European twin register with a projected 600,000 members is being organized, but one of the largest in use is in Australia, with more than 25,000 twins on the books.”

A significant twin study among adolescents shows an even weaker genetic correlation. In 2002 Bearman and Brueckner studied tens of thousands of adolescent students in the U.S. The same-sex attraction concordance between identical twins was only 7.7% for males and 5.3% for females—lower than the 11% and 14% in the Australian study by Bailey et al conducted in 2000.

In the identical twin studies, Dr. Whitehead has been struck by how fluid and changeable sexual identity can be.

“Neutral academic surveys show there is substantial change. About half of the homosexual/bisexual population (in a non-therapeutic environment) moves towards heterosexuality over a lifetime. About 3% of the present heterosexual population once firmly believed themselves to be homosexual or bisexual.”

“Sexual orientation is not set in concrete,” he notes.

You wanna know how it's not genetic? Look at places like San Francisco. Why are there more gay people there than in other areas? It's promoted over there.....it's almost become a lifestyle choice.

They are all natives?

No. I guess I should have clarified that. There are gay folks that move there because it's more accepted. But a lot are native. My wife is from the Bay area. She has six gay people in her family. Most of her frineds families have gay people in them. I'm from Texas, and do not have any gay members in my family(that we know of). Coincidence?

Well..ya..already knew that.

These studies are hardly controlling for all the variables.

Question 1: What percentage of people with same sex attraction accept those feelings and adopt a gay lifestyle? This variable is huge. I would venture a guess that there are many many many "straight" people out there who are just going through the motions and refuse to admit to themselves that they have same sex attraction. Some stay single their whole lives, some get into straight relationships and maybe even fall in love with opposite people of the opposite gender. But they don't have "attraction" to their partner in purely instinctual way. There really is no way to isolate this variable, and all the studies become junk afterwards.

Question 2: What percentage of the gay population is living a gay lifestyle, despite the fact that they primarily have opposite sex attraction? These people may or may not be "gay" because of a particular fetish they have picked up, or because of other environmental factors that amount to a type of peer pressure. Or perhaps, they were curious and just happened to come across a great sexual partner, or they fell in love with someone of the same sex, and became gay despite the fact that they primarily have OPPOSITE sex attraction. Again, impossible to tell what motivates these things, and the study becomes moot.

Question 3: Is it possible to hold BOTH same and opposite sex attraction instinctually? We know that there are bisexual people out there, but is one nature, and one nurture? We have no way of knowing. And studying twins doesn't help, because one twin could easily be ignoring one aspect of their sexuality.

Question 4: What is the agenda of the people studying the phenomenon? What exactly are we trying to find out here? Are we trying to prove that being gay is genetic? What would that prove? Would that legitimize the lifestyle, or damn it further? Hodgkins lymphoma is genetic, and we're looking for a cure.

Question 5: Are we even certain that being STRAIGHT is genetic? What part of the genetic code is responsible for THAT? Oh, that's right... We don't know.

You have to lay bricks all your life to be called a brick layer. Suck one cock, and you're a one who sucks the penis for life.

Dr. Whitehead's backers.

Also, the basis of his study is bullcrap.

I don't understand why it matters if homosexuality is genetic or not. Even if it was a choice, that would not be a reason to discriminate. People are allowed to make choices about their own lives in our society.

San Francisco was the first major metropolitan area to ban police raids of gay bars and nightclubs. Hence the gay population quadrupled within a decade. You're a dumbass.

There is no way being queer is a choice. If someone put a gun to my head, said okay you have to be gay now, you have to ram that dude in the pooper. I physically COULD NOT do it no matter how much I "wanted" or "needed" to. They'd have to shoot me. It would just be hanging there all limp. I don't know how that is difficult for anybody to understand. It's clearly not a choice, whether they were born gay or not is debatable, but it's NOT A CHOICE.

Could it be because texas isn't quite as accepting of openly gay people as some other parts of the country?

Probably afraid of being lynched?
