I don't believe the networks have any interest in the Parents TV Council, considering how much those folks drive them nuts.
As to the current issue, here's my opinion, short and sweet.
To Wildmon's Whiners who think a very bold accounting of a very real event is 'obscene', get a grip.
To those CBS affils that are running scared, get a spine.
To the FCC, tell the whiners "Get Lost!"
BTW: I haven't seen any promos for this airing as yet, but if I were CBS I'd make damn sure the ratings bug appears more prominently than usual. It should appear on the "billboard" at the END of the spot, and it should be announced ("Rated TV-whatever") with the Viewer Discretion note. This should be standard practice for all concerned. It's been required for years in all ads for theatrical movies.
This show's airing at 9/8 PM, which by now should be regarded by all as the time when the most edgy fare will (should) run. Responsible parents know what they should do. Those that aren't should know better.
