The bottom line is:
There are rules and, though the FCC may be working its way thru the issue of how to enforce them and how you interpret the offenses when they occur, the facts are the facts.
Some college students who feel it's their "artistic" right to use music with foul language to make their points may just have to learn the hard way that the "rules" say you can't use such language on over the air radio. (Though there is the "safe harbor" rule, which will allow a certain amount of "rule bending" at a time of day when the youngest of the young are not "supposed" to be listening to radio.)
I'm sorry, but I can appreciate the views of a parent who doesn't want their 9 year old kid exposed to F-bombs and N-bombs and B-words, etc. over their local radio stations during most times of the day...even if the kid has heard those words and uses them. Moderating that is the parent's job (and some parents do a lousy job of that!)
Yes, I can also appreciate the "if you don't like it, change the channel" argument. But, just try to make listeners understand that. It ain't easy, trust me. We just can't live in a system where there are no rules.
