General Discussion
In reply to the discussion: Abortions motivated by a fetus's perceived homosexuality. [View all]People just aren't so petty.
Also, there is no test and it is pretty clear there never will be - if identical twins quite often differ in sexual orientation, it is not a fixed genetic thing that we could ever test for (like Downs Syndrome). See the Swedish all-twin study:

But even if there ever were such a test, I don't think people would abort most those children.
Quite a few people know that their children have Downs Syndrome, but don't abort the baby. Downs kids have always seemed to me to be able to live very happy lives. As a parent, that is what would make the difference for me.
I don't think most people perceive having a same-sex orientation as being a characteristic that dooms a person to a tragic, tortured life, so I think you are wrong.
