Lacks, no one has suggested that conservative ideas should be censored (censured, probably...but that's only common sense). What is being suggested is that for every hour Limbaugh has to spew his distortions and half-truths, the same station needs to allow equal time for argument/rebuttal. It's not a squelching of one side, it's an airing of both sides.
That being said, I'm sitting pretty high on the fence on this one...
Speaking of which, anyone know if the rules of the 'doctrine' would cover BEN, since they also have 1520? Does it have to be the same station, or just the same company/coverage area?
