Mothers' genetic skew linked to gay sonsand
Homosexuality is biological, suggests gay sheep studyNothing conclusive so far, but it is looking to be genetic at this point.
What does this mean for our future, as queer people? Is being queer a defect? I personally don't see how it is in a modern world, although it is arguable that queer subcultures have not stabilized adequately to be a stable element in society (although, much of that is because of the persecution we suffer).
Inevitably, though, there are those who will wish to preemptively screen out children affected by genetic skew which will lead to them being gay. There are those who would love to live in a state where such filtering were mandatory. And at that point, what would it take to immigrate to such a state or country? Borders have been slowly becoming less and less meaningful. I feel, perhaps naively, that there is a growing feeling of international brotherhood and community which would be destroyed by a country which routinely alters certain genetic things.
Regardless of all that, I do feel a prick of concern. Will we be hurt by the progress of science in this category (not that we can stop it)?
Also, what do their findings mean for bisexuality?
