If it is genetic then abortion only covers potential offspring. Why not just kill the parents that carry the gene? This is gonna get messy. Or would they do a twofer to get more money, kill the baby first and then kill the parents separate? This would also suggest that Heterosexuals are responsible for homosexuality, or that homosexuals pretending to be heterosexuals have kept homosexuality around far longer than it would have lasted if the gays were free to gay, though they are often killed in other places so it's gotta be the breeders, right?
