Let's say, in the future, scientists discover that homosexuality is genetic. They also are able to diagnose embryos that have the homosexual gene, so it is then possible for women to know if their child will be gay. They're already able to do that with embryos with a dwarf gene. Should it be all right for a woman to have an abortion to prevent an unwanted homosexual child from being born?
Some think that this question is complex, but it isn't at all! It can't be clearer: if you're pro-life, then it would be wrong for the woman to be able to have an abortion even if the child will end up gay, and if you're pro-choice, then it would be wrong to forbid the woman the right to have an abortion because the child has a gay gene.
If you think life is sacred, then it doesn't matter if an embryo has a certain gene or not, so to support an abortion then would be the ultimate form of hypocrisy. And if you think that it's the woman's choice, then you shouldn't try to take away that choice when you disagree with it. After all, according to the pro-choice community, it's the woman's body, it's the woman's choice, the embryo is not a human being, and denying a woman her reproductive rights is a violation of her civil rights.
That was simple.
