The way I look at it is, it depends on where the obscenities are coming from, how they're used, etc. For example:
Exhibit A: "What we may discover with the LHC could help us understand and account for important debated discrepancies in modern psychics. We could even learn more about the formation of our own universe. This is an absolute phenomenal opportunity and I personally believe it's worth a little fucking risk!"
Exhibit B: "Fuck dat booty, fuck dat booty ho, fuck dat booty, shit, money, shit, gold rims mothafucka, yeah"
So, in a way, I sort of pretty much agree with Σεληνόλυκος. Useless expletives in useless conversation only degenerates the listener even worse. Kids are fucking morons these days because they're listening to morons. However, allowing someone to add the occasional expletive in MEANINGFUL, INTELLECTUAL debate would very well serve to lighten the mood a little and probably provide much better, more genuine interviews. The listener isn't degenerated when the core conversation is truly intellectual simply because someone uses a "four-letter-word".
What should *REALLY* be abolished is 90% of media directed at tweens and teenagers.
...And I think I sound like my father now.
