AAABEST:Although there is a point where a "violation" occurs. If a parent can't get up and make popcorn without having to worry that his 8 year old is going to be presented with a situation where a nasty whore is having sex with a horse, well we have a problem. Adults choosing such is one thing, kids are another.
I think the popcorn example is a legitimate concern.
I view the public airwaves similar to public spaces -- e.g. roads, sidewalks... I would imagine there are various local laws that forbid certain actions in these public spaces. A few of these laws are good -- no indecent exposure on the corner of 5th & Pine -- and many other of these laws regulating these public spaces are not so good.
IMO, these same reasonable laws(not the many unreasonable ones mind you) that control public behavior in public spaces and the mechanisms that bring these laws about should also apply to the public airwaves.
If you want to see sexually explicit behavior, the place to see it is on private cable(although cable is not totally private) and not on the public airwaves or on the corner of 5th and Pine. The mechanism for such laws should be legislative and not a agency regulation -- shut the FCC.
The only alternative is either anarchy or an overbearing government agency.
