If a biological basis is found, and if a prenatal test is then developed, and if a successful treatment to reverse the sexual orientation to heterosexual is ever developed, we would support its use as we should unapologetically support the use of any appropriate means to avoid sexual temptation and the inevitable effects of sin.
Lots of folks are upset about this. I'm not sure I am. I would strongly oppose government-mandated treatment of fetuses to ensure heterosexuality, but I don't think I could fault parents for wanting their babies to be straight, given a reasonable choice. While I don't think homosexuality (including homosexual sex) is immoral, there's no doubt that being homosexual can be challenging and if parents want to spare their children that particular difficulty, I don't see what the problem is. It would be kind of sad and possibly harmful to have less sexual diversity in the human race, but I don't think that is sufficient reason to disallow it.
What about genetic/hormonal treatment for other traits? As science progresses, we might be able to alter fetuses in ways we can now barely imagine. I wonder whether Rev. Mohler would support parents who want to treat fetuses for tendencies towards being religious, for example?
Which of the following traits should parents be allowed to alter, assuming a treatment becomes possible? Which should they be encouraged or discouraged from altering?
- Fatal disease
- Chronic but manageable disease
- Eye/hair color or other minor cosmetic changes
- Deafness/blindness (preventing or causing, as some deaf parents might wish)
- Tendencies towards addictions, obesity, or anorexia
- Tendencies towards being generous
- Athletic ability
- Tendencies towards or away from religion
- Tendencies towards or away from fundamentalist thinking
- Skin color, epicanthal folds, and other distinguishing racial characteristics
- Lactose intolerance
- Tendencies towards happiness or optimism
- Tendency towards political party
- Tendencies towards wanting to be a doctor
- Having six fingers or toes
- Musical ability
- Sexual appetite or lack thereof
- Tendencies towards introversion/extroversion, conscientiousness, openness, agreeableness, or other personality traits
