Are you suggesting that there are no people in Oz who object to profanity and nudity? Profanity and nudity don't appear on the public air waves precisely because cable and satellite television are available. Before the mid-1970s, the "Big Three" (NBC, CBS and ABC), along with PBS and a handful of independent local stations were all the choices one had for television, unless one was on the Canadian or Mexican border. Then cable companies began to spread like a rash, and the prevelance of profanity and nudity increased, especially after Home Box Office started up. But there are a lot of "family values" types in the United States who don't want to see that on the television--so the open air broadcast networks still eschew those things, and everybody gets what they want.
It gets tedious to be constantly told how inhibited we are, or that we don't understand irony, or that we lack a sense of humor, or whatever, on and on and on, by people who don't live here and really don't know what the hell they're talking about.
