When was the last time Letterman found something a female teen did that was maybe worth a positive mention on his show?
It would seem to me that not only is it wrong to make sexual jokes about underage females for public consumption and profit on a national TV show, it seems even more inappropriate because no time is spent on Letterman's show discussing positive underage female role models.
If the obvious answer is, well it would be boring to talk about underage female teens in a positive way and make it funny and interesting, then maybe David Letterman and his writers have become too old school and behind the times.
I found Mr. Letterman's follow up non apology to be actually worse than the original Willow Palin joke he was apologizing about. Mr. Letterman had time to think about his response and come up with something wise and profound to say, yet once again, Letterman and his writers fell short and literally gave the message that they just didn't think it was that important to properly address his avarice against female teens.
Maybe Letterman, short of being fired or suspended, devotes a week to teenage girls as guests on his show. It would be interesting to see if Letterman can handle these teenage encounters in a way that is non-destructive. It would be even more amazing if the some of the commercial content would be aimed at young teens and the real issues they are going through.
