Good for the FCC. They control the public airwaves, and until such time as they don't, people have to abide by the terms of the licenses they hold. No pissing in the public pool.
So what are the standards? Where is the line- should anything that I, as a black woman, feel offended by be put off the air? I have listened to Stern's show a few times, found him offensive and not very funny, so I TURNED IT OFF. I don't believe in running to mommy government every time I see something I am offended by.
