I wouldn't like to see the return of the Fairness Doctrine, but I worked in television when it was in force and I recall that it only required equal time to other views. It didn't require a point-by-point rebuttal of anything, unless that's what the folks who claimed the right to respond wanted to do. In practice, at least at the station where I worked, local citizens groups didn't demand use of the equal time. But that was in the 1970s. I suppose they would today, and might want to do a point-by-point. Then, as before, I suppose, the main worry would be whether stations would allow themselves to be subjected to all this by airing controversy in the first place.
