People swear on TV all the time.
They do? Seems to me, that except on specific cabel channels, they get bleeped all the *bleeping* time.
PS: I don't think the ability to turn the filter off at a personal level was there when I joined this site years ago. That's why I was surprised.
Sorry, I'm from the Netherlands. I don't think there is anything they cannot say on TV here. Seeing shows like South Park and some American stand up comedians, I assumed that it was allowed in the US by now too.
Or is the reason that they swear so much exactly because it isn't allowed on TV. That it's still a "cool" "rebellious" thing to do?
Depends on the channel. Some channels are "aired" so the FCC tended (note the past tense there) clamp down on that sort of thing. Cable broadcast follows a different set of rules. If it's "free" (the context of free is pointless, but I'll use it here) tends to be censored similar to aired stations. Pay stations tend not to be censored so that's why stations like HBO, Cinemax and Playboy air what they air without censorship.
IIRC, George Carlin drove the FCC to ban ---steaming pile of meadow muffin---, Piss, ---fudgesicle---, ---Bad words, bad words, whatcha gonna do? Whatcha gonna do when saint censors you?---, ---Bad words, bad words, whatcha gonna do? Whatcha gonna do when saint censors you?---, ---maternal-smurf---, and Tits. When I was in school, this was expanded to ten or twelve basic words not including the variations. Can't remember what they are anymore though I think cum and ---smurfette--- were on the list.
This is a point shows like South Park (as you mentioned) keep rubbing in with their famous "---steaming pile of meadow muffin---" episode as well as Family Guy and to a lesser degree, The Simpsons and dozens of others. A lot of people think it's an archaic concept so they try to slip this stuff into their shows.
I agree to some degree about censoring "nasty" words, but I think a lot of people have completely missed the ball on what's going on. The introduction of the internet completely breaks down any restrictions found on over the air broadcasts. Seriously, there's a reason the Sears catalogue isn't published anymore. For over a hundred years, the Sears catalogue was the first jerk mag a majority of male teens experienced. With the internet at their fingertips, teenagers can get the kind of that makes every nosey ---smurfette--- church woman spin in their graves and make Larry Flynts mag look like Sesame Street cred. (I'm also of the belief that Xiaou2 can get his free energy if he can somehow figure out how to harness the rotational energy of these church going corpses.)
Cussing is pushed pretty low on the priority list when I have to explain to the nine year old about Goatse or Bathtub Girl that she may see on the screen.
