I get a distinct feeling that a big proportion of the No voters simply want that entire race to die out by itself. Become extinct from their self-destruction spiral. There's no need to ask them for an alternative solution because they don't have one and quite frankly, aren't seeking one.

Let's not pussy foot around it. I think deep down inside that's what a lot of people here in Australia want. They did the hard yards, made it to this "garden of Eden", now there's a sickly thing in the garden that they could either sacrifice some of that garden to save, or they could just let it die on its own and have the garden all to themselves. Many would choose the latter!
