"We should always be disposed to believe that that which appears white is really black, if the hierarchy of the Church so decides."
Before Nova this evening, there was a "mature content" warning.
Nova tonight discussed an ongoing controversy regarding the origin of the original human inhabitants of the Americas. In brief, it discussed the long-standard "Clovis-first" theory in the light of new archaeological finds, conjectures based on analysis of tools from ice age Europe, and evidence from analysis of mitochondrial DNA.
In short: About as hard-science as archaeology gets. Finding the bones, finding the tools, big-time.
During the entire program, there wasn't a single bare breast, not a single blue word or phrase, not one mention of gay marriage or even a hint of sexual liaison (aside from the implication that the ancestors of modern native americans might have, you know, reproduced).
So why the mature content? Is it, perhaps, that they're scared that some religious fanatic might point out that when you're talking about things that happened 15,000-20,000 years ago, you're pretty much assuming that the world is older than 4,000 years -- hence insulting all the KJV Baptists in the Nova audience?
By contrast, consider any random episode of Law & Order: Elevator Inspectors Unit, or CSI: Sheboygan, wherein you're likely to find references to "last meals" of semen or violent sexual deviance. I don't recall ever seeing a "mature content warning" before either of those shows. Ever. But then, they don't challenge the Dog-given age o' the universe....
