You are assuming that people who watched the halftime show are USED to watching MTV.
THE POINT is, that display was totally inappropriate for the audience. Period. People who want to see this kind of thing can choose to do so. Aren't libertines always saying to those who object, "Well, if you don't like it, change the channel."?
Most parents assume they can watch a sporting event without being subjected to trashy sexually explicit displays by no-talent "celebrities". It doesn't take a great deal of talent or imagination to take your clothes off in public. Only a below average IQ.
Actually, I've had to ask my husband to be sure and turn the channel during commercials while watching football games so that our 6- and 8-yr-old sons don't see any of the offensive commercials.
The sad thing about this whole half-time assault was that people even kept watching when the exhibitionists started their x-rated antics. I missed the "grand finale" because I couldn't take the *crap* leading up to it. Unfortunately, too many of the teenagers from my little Houston suburban town were in the "fake crowd" for the whole thing. I don't think their parents knew they'd be close up to a virtual orgy...
