And yet, the moments in which religion is portrayed as being genuinely, rather than opportunistically, important to Flanders undermine this subversiveness, and I wonder if there is some extraneous "balance" agenda at work.
I don't think it's so much a "balance agenda" as it is that the Simpsons is one of the few shows in history that really sees the ridiculousness of all sides in any given situation.
One of the best examples I can think of is the medical marijuana episode. While the episode definitely came down on the side of legalization, it also had a hearty sense of how generally silly the subculture of drug legalization is. The two big moments that made me laugh my ass off were when Homer says, "Whether you've got glaucoma, or you just rented the Matrix..." and when Phish stopped playing at the legalization rally, sniffed the air, and the singer said, "Is that pot? Okay, we'd better see a doctor's note, or Phish is out of here!"
All in all, it gave off a vibe of, "yeah, we're for drug legalization, but we know that part of the reason for it is because people want to get toasted, eat a whole bag of chips, slap on
Dark Side of the Moon, and giggle their ass off at Scooby Doo. And you know what? We can laugh at that."
Same deal with Flanders and Christianity. The Simpsons generally comes down on the side of Christianity being a sorta lurching beast of a religion, but at the same time, there's comedy to be found in scenes where Flanders is totally
right about God. For instance, the bowling league episode... specifically the bit where Ned only knocks down nine pins, and Homer begins to laugh at him. He calmly whispers, "It's me! Ned!" and the tenth pin falls down of its own accord. No matter your position on Christianity as a whole, that scene's still damn funny. And in order for scenes like that to work logically, it has to be established, at least elsewhere in the show, that Ned really is honest about his religion.
Anyway, that's the point I'm circuitously meandering towards here... the biggest "agenda" on the Simpsons is comedy. And any end of the political or social spectrum is fair game.
