@Brandon9000,
I think Joe did most of the heavy lifting in this round of the argument. (Thanks, Joe!) But in addition to seconding his important point that precedent matters in law, I disagree with your flat-out statement that authority is irrelevant in a discussion. Far from it! Appealing to authority is perfectly okay whenever authority is a reasonable proxy for competence.
Think about it: On the one side of
Loving v. Virginia, you have nine jurists, all of excellent standing within their profession. Between the nine of them, they have man-centuries of job experience in constitutional law. Although their politics differ greatly, as do their judicial philosophies, their conclusion is unanimous: Prohibiting interracial marriages is discrimination, and violates the Lovings' constitutional right to equal protection under the law. On the other side of the case, you have a computer programmer who's interested in current affairs. By his own account, he looks at the case "for a minute". "Based on [his] quick scan of the thing", he then concludes that "the reasoning seems to be wrong".
How isn't this a good reason to presume that the Supreme Court got it right and you got it wrong? Not mathematical proof, I admit, but good-enough evidence to establish a presumption? And, to rebut this presumption, shouldn't we demand better arguments from you than a snap judgment from the seat of your pants? As a computer programmer, how much patience would you have if a newbie showed up in the newsgroup comp.lang.c and commented on a statement from
Brian Kernighan the way you're now commenting on an important Supreme Court decision?
