There was an article in Time many yrs ago where some genetic scientists are looking for genes that determine personality traits. They specifically stated there could be genes that determine a person tendency toward criminal behavior and homosexuality. If there really is such a thing as a “gay gene” or a “mean gene” all the hand wringing about medical ethics will not prevent the cat from being let out of the bag. Then it will only be a matter of time when a woman seeks an abortion because her doc told her the unviable tissue mass inside her may turn out to be criminal, or gay, or both. THEN let’s how many pro-choicers become pro lifers overnight.
There was an episode of a short lived TV show, “Future City”, with exactly this premise. If you could terminate for any reason, why not homosexuality?
