Because dead fetus can be used for a variety of household chores. I just have to find some.
Now please don't try to derail the thread
I'm not trying to derail anything. I am pointing out a basic logical contradiction here that I can assure you would be one of the first things to come up should medical science actually find a way to detect and change sexual orientation in the womb. Or, for that matter, to change anything genetic in the womb.
We have made a societal mantra out of "a woman's right to choose" an d the idea that abortion is about "what a woman does with her own body" until people parrot it without even thinking any more. The fact that a fetus is not in any sense a part of the mother's body rarely impinges on people's consciousness when their eyes glaze over and they start spouting PCisms on the subject. So for anyone who supports that position to now suggest that when it comes to sexual orientation, that fetus is a separate person with a right to future self-determination that the mother should not infringe upon, that essentially the mother has the right to choose to kill him but not the right to choose to make him heterosexual, is ludicrous and hypocritical. Killing him is okay, but we're going to balk at customizing him?
Pro-lifers have a leg to stand on if they want to object to "designer babies", because they've taken the position that fetuses are living beings possessing basic human dignity. Pro-choicers are pretty well locked into the idea that the mother has the right to do anything she wants to that "unviable tissue mass", including treating his genetic homosexuality as a disease to be cured.
