Which well-known homosexuals?
What is your opinion on Gay adoption, you're querying others stating they are in favour of it without detailing why you're against it.
How many adoptions are there in this country every year compared to the numbers seeking adoption? I don't think there's a huge surplus of those seeking kids over those seeking to be adopted, so the Sophie's Choice you're positing is unlikely to come to pass. It's just trying to muddy the waters. I wouldn't have a problem with the people who currently decide on adoptions continuing that role when the pool of potential parents is expanded by this legislative change.
Also Firefly there's no need for a referendum on "gay" adoption, it's not in the constitution.
