Every once in a while I run into someone criticizing the Bible because it contains some depiction of someone doing something immoral, usually when the text never endorses that act or even if it's clear from the general context that the narrator considers the act downright evil. For example, Richard Dawkins objects to the story of Jephthah's rash vow, that if God gives him victory he'd sacrifice the first thing coming through his gates to greet him as he returns home, only to be greeted by his daughter, so he sacrifices her. His reason for objecting? Well, Jephthah did something obviously wrong. So the Bible must not be a good guide to immorality.
As has been said many a time, Dawkins would fail an introductory philosophy or religion course if he submitted materials from his book or similar quality work for such classes. This idea that the mere inclusion of an immoral act in a narrative somehow makes that narrative immoral is downright crazy. No one really believes that. Murder mysteries would suddenly because evil, for instance, because a murder does take place in them. You couldn't have crime-fighting stories of any sort, because those would contain evil acts to be fought against.
Nevertheless, despite this idea being absolutely ridiculous, it apparently comes up in contexts that have nothing to do with the Bible. There's been a campaign against the forthcoming Stargate Universe, the third (and I think what may well be the best) series in the Stargate franchise. Darren Sumner of Gateworld has an excellent discussion of what these objections are and why they fail completely.
Aside from the fact that it's pretty dumb to criticize a show you haven't even bothered to wait to see when you have at best partial information, the argument itself seems silly. It's been rumored that there will be some temporary body-switching, with the consciousness of one person controlling the body of someone else in a different galaxy (which the Stargate franchise has done several times before), only this time the controlling parties will have sexual encounters using other people's bodies. That raises obvious moral questions, in particular if the owner of the body in question didn't consent to have their body used this way. But merely depicting them something doesn't imply endorsement, and it's almost certainly true (given what I know from the Stargate writers) that they will want us to question whether this is ok, again assuming no consent (and we haven't been told if there will be consent to use each other's bodies this way by mutual agreement, which for all I know will be part of the arrangement).
The claim (see the comments) is that it's rape, and they shouldn't be depicting it. Well, we don't know if they'll be depicting it. But they do depict rape on Law & Order: Special Victims Unit, or at least they sometimes come close enough. They did depict rape on Battlestar Galactica. There were people who objected to the latter, but I never understood why the mere depiction of rape, especially when it's absolutely clear that the people doing it are being downright evil, is somehow wrong. It was, in that case, an easy way to show the morally degenerate state of the Pegasus crew under Admiral Cain's command. The Galactica crew were certainly not perfect, but the Pegasus crew had gone well over the edge to true evil. That scene made that abundantly clear, and it was good storytelling.
The difference here, as some commenters in that thread point out, is that main characters carry this out. But main characters can be morally flawed in a good story. They can even be pretty evil. Why is it immoral for a storyteller to have a main character do something as bad as raping someone? I see no argument for this claim anywhere in any of these discussions.
But comparing these two kinds of fallacious criticisms at least helps me understand that such shoddy thinking isn't present just among those seeking to have any argument, no matter how bad, against the Bible. Those who want to have any argument, no matter how bad, against a forthcoming TV show will resort to the same tactics. So maybe this isn't a problem just among those who want to attack Christianity, the Bible, or religion. It occurs much more generally than that.
