What's Indecent: Nipplegate or 'Gossip Girl'?

From the "Will nobody think of the children?" department:

CBS is battling in court to get back the $550,000 fine it paid after Janet Jackson flashed one breast for a split-second on national TV.

Meanwhile, over on the CW network, which CBS half-owns, teenagers are drinking martinis, smoking pot, having sex and wearing Prada on the new series Gossip Girl. "It's aspirational," says Cecily von Zigesar, who wrote the books on which the show is based. She's referring to the fashions, not the alcohol, drugs and sex. Got that, 14-year-olds? Covet the styles, abhor the lifestyle.

And unlike CBS, which had no advance knowledge of Jackson's stunt, the CW knows exactly what's going to happen on every episode of Gossip Girl.

Can someone explain this to me? If I were a parent, I'd much rather have my adolescent kid catch a brief, blurry nipple-flash than watch glamorized versions of her peers getting wasted and laid. But in the F.C.C.'s view, the former is indecency, and the latter is just entertainment.
