OMG, being gay is a CHOICE not a BRAIN DEFECT!! God does not accept gay men into heaven, so why would he create man like that??

I'd still like you to put your theory to test. See if you can become gay by changing your neuro paths in your brain. Let us know how it works out.

This is my basic problem with the idea that Homosexuality is genetic: for millions of years evolution has designed humans for 1 thing Species SURVIVAL!!! And our basic functions of life include survival, food, and reproduction. So why would evolution possibly allow our genetic code to allow for homosexuality, which in essence would be a viloation of what evolution designed us to be. Evolution designed us to pass our DNA on to the next generation for the survival of the species (like all other species) so why would it possibly have another gene hardwired into our brains that allows the species to be dysfunctional that would "tell" the brain that for the continuation of the speices (sex) you must mate with the same sex. It doesn't make sense why evolution would allow our genetic code to do that, now i know that our genetic code isnt perfect, but for the basic functions of the body our genetic code functions properly it operates pretty damn good.
There are many scenarios that could explain a genetic influence for homosexuality.
It is possible that some genes that provide an evolutionary adaptive trait in the mother could, in some circumstances, result in homosexuality in their male offspring. For example, if there are genes that promotes fecundity in the female but may result in a proportion of homosexual children. It needn't be a direct selection for homosexuality (like the genes underlying sickle cell actually provide protection against malaria)
Then it could also be a sort of 'worker bee' altruistic type selection. There is evidence that in large families the later children have a higher proportion of homosexuality. These children would aid the family through promoting survival of the other offspring, so although, the homosexual's reproductive fitness is low, the others in the familial group would be of increased fitness.
It could just be that when a certain group of individual alleles are expressed in a particular person (or certain mutations) the result is homosexuality.
So we need to look at group level fitness and secondary effects of genes. We also see homosexuality in other species, sort of kills the pure social learning approach. It will likely be an amalgam of environmental and genetic factors.
Oh, and homosexuals can reproduce if they like. Many do

It seems that there's no limit to the hatred humans can express.
The quest for a cause to homosexuality is the quest to relegate homosexual persons to second-class status, to explain away their very existence as a mistake or genetic fluke, and take away their humanity.

I also wonder if there is a same study for pedophiles. maybe they got major defects too in the brain that might explain their preferences.
