I think this whole business has been given far more press than it deserves. As a Celt, I would love to have a little more color in my skin. It's normal to speculate on how an unborn child might look, dark eyes, or pale, curly hair or straight, tall or short,..the list goes on. I see nothing racist in these speculations.
As for the royal family, they have outlived their usefulness, if they ever had any. Time to retire them. When the queen passes on would be a perfect time to close the books on them, and their baggage.
