"Family Guy" is puerile filth. The Geico ad is pretty disgusting too.
In the ad though the young woman is the sexual aggressor (which means it was focus-group tested for the Sandra Fluke customer base)
I agree completely with your observations. Television and the commercials sponsoring the flotsam and jetsam appearing on the screen are evidence of a degraded culture. It accelerated with the beatnik and hippie era of the 60s and got even worse (as if that were possible) when urban blacks started the hip hop and rap "culture" which was, sadly, embraced by suburban whites.
Furthermore, GEICO stands for Government Employees Insurance Company. That tells me everything I need to know about this vile outfit and their equally foul advertising. Disgusting doesn't begin to describe the "vast wasteland" we have in 2013. EWTN and Fox Business are about the only channels worthwhile, aside from an occasional classic, patriotic movie on TCM.
