Skeptic says:

Brian, you have easily covered “my” side of the argument. You think murder is acceptable solution for stupidity… where your hypothetical husband is so stupid he marries someone he knows essentially nothing about, and the “wife” is so stupid as to enter a marriage without being up front about her sex change.

Try reading something up to date (2010 vs your 1957 opinion) on the genetics front. You may be enlightened, but I’m not betting on it.
“The fetal brain develops during the intrauterine period in the male direction through a direct action of testosterone on the developing nerve cells, or in the female direction through the absence of this hormone surge. In this way, our gender identity (the conviction of belonging to the male or female gender) and sexual orientation are programmed or organized into our brain structures when we are still in the womb.”

“In July 2010 a group of geneticists at the Korea Advanced Institute of Science an Technology altered the sexual preferences of female mice by removing a single gene linked to reproductive behavior. Without the gene, the mice exhibited masculine sexual behavior and attraction toward urine of other female mice. Those mice who retained the gene fucose mutarotase (FucM) were attracted to male mice.”

But even using plain old common sense it is obvious that there is genetics at play with most homosexuals. have a look at the physical traits recorded in scientific studies to date, which I have borrowed from Wikipedia… all cited with published papers.

Gay men report, on an average, slightly longer and thicker penises than non-gay men.[50]
Gay men and straight women have, on average, equally proportioned brain hemispheres. Lesbian women and straight men have, on average, slightly larger right brain hemispheres.[51]
The VIP SCN nucleus of the hypothalamus is larger in men than in women, and larger in gay men than in heterosexual men.[52]
The average size of the INAH-3 in the brains of gay men is approximately the same size as INAH 3 in women, which is significantly smaller, and the cells more densely packed, than in heterosexual men’s brains.[31]
The anterior commissure is larger in women than men and was reported to be larger in gay men than in non-gay men,[30] but a subsequent study found no such difference.[53]
Gay men’s brains respond differently to fluoxetine, a selective serotonin reuptake inhibitor.[54]
The functioning of the inner ear and the central auditory system in lesbians and bisexual women are more like the functional properties found in men than in non-gay women (the researchers argued this finding was consistent with the prenatal hormonal theory of sexual orientation).[55]
The suprachiasmatic nucleus was found by Swaab and Hopffman to be larger in gay men than in non-gay men,[56] the suprachiasmatic nucleus is also known to be larger in men than in women.[57]
The startle response (eyeblink following a loud sound) is similarly masculinized in lesbians and bisexual women.[58]
Gay and non-gay people’s brains respond differently to two putative sex pheromones (AND, found in male armpit secretions, and EST, found in female urine).[27][59][60]
The amygdala, a region of the brain, is more active in gay men than non-gay men when exposed to sexually arousing material.[61]
Finger length ratios between the index and ring fingers may be different between non-gay and lesbian women.[55][62][63][64][65][66]
Gay men and lesbians are significantly more likely to be left-handed or ambidextrous than non-gay men and women;[67][68][69] Simon LeVay argues that because “[h]and preference is observable before birth[70]… [t]he observation of increased non-right-handness in gay people is therefore consistent with the idea that sexual orientation is influenced by prenatal processes,” perhaps heredity.[31]
A study of 50 gay men found 23% had counterclockwise hair whirl, as opposed to 8% in the general population. This may correlate with left-handedness.[71]
Gay men have increased ridge density in the fingerprints on their left thumbs and pinkies.[71]
Length of limbs and hands of gay men is smaller compared to height than the general population, but only among white men.[71]

If these obvious physical traits don’t doesn’t you that there is a genetic connection (and that it’s only a matter of time to find the genetic markers), then I suggest you have your DNA tested for the ‘stupid’ gene.
