Andrew, whats up with Scalia's opinion?
This is a very difficult question to answer because it will require such a wide swath of background and understanding to develop properly. Simply by asking this question, it shows me that we're not on the same page. So please forgive me as I devlove into a history lesson...
First, it will help to realize that about 23,000 years ago, a small race of extraterrestrial beings voyaged to Earth from their distant planet in orbit around the star Omegadeltagamma-29236. This isn't related to Scalia in any way, but it's important to know.
Second, the ancient egyptians developed time travel. Because of this, we can't say when they did it. Did they develop it in the future and travel back to show their past ancestors how to do it? Who knows. The point is that there are ancient egyptians buggering around with spacetime. This sends ripples backwards, forwards, left and right, in all 11 dimensions. One of these ripples ran into the sperm that would eventually become Scalia, warping its structure slightly. Result: Scalia isn't totally human.
Third, because of the proto-scalia sperm's encounter with the ancient egyptian time ripple, the present Scalia possesses uncanny powers to peer into space and time. He knows the future, you see. His opinions actually represent the best and brightest course for humanity, and it's his eternal pain that we don't follow his guidance more often.
