as you wish.....
science has been trying to prove homosexuality a
physical trait for over 40 years now (
this from one of your links) unsuccessfully
There is no '
gay' gene, there is no normally alternate DNA , nor are there any
physical brain characteristics
Otherwise sexual
preference could be determined
in vitro
Follow so far?
No. Still not following. Just because there is no definitive discernable cause doesn't mean there isn't evidence of all of those things you described above.
Homosexuality - Wikipedia
Although
no single theory on the cause of sexual orientation has yet gained widespread support,
scientists favor biologically based theories. There is considerably more evidence supporting nonsocial, biological causes of sexual orientation than social ones, especially for males.
Despite numerous attempts, no "gay gene" has been identified. However, there is substantial evidence for a genetic basis of homosexuality, especially in males, based on twin studies; some association with regions of Chromosome 8, the Xq28 locus on the X chromosome, and other sites across many chromosomes.
Biology and sexual orientation - Wikipedia
The action of the SRY gene in the Y-chromosome in the fetus prompts the development of testes, which release testosterone, the primary androgen receptor-activating hormone, to allow testosterone to enter the cells and masculinize the fetus and fetal brain. If a sufficient amount of testosterone is received by INAH3 at 12 weeks following conception, the testosterone stimulates the enlargement of INAH3, which is known to be involved in directing typical male sex behavior, such as attraction to females. If INAH3 does not receive enough testosterone to override the circulating estrogen, it may not grow to the size typically observed in males. Subsequently, INAH3 may function as female or partially female, potentially causing same-sex attraction to males. Although, the size of INAH3 in homosexual men compared to heterosexual men may not be statistically different, though homosexual men may have a greater cell density, that is, more cells per unit volume, but a similar total number of neurons in INAH3 than heterosexual men.
Ergo, there is only that which is psychological
A phenotype being the observation of a genotype being just that goat

Just saying ergo doesn't mean you've come close to making any sort of rational point. Nice try though.
