Limbaugh and Beck - why are people on this site (and elsewhere)?

so up in arms over these guys? I am a moderate conservative - not a flamer- and I don't listen to those people. They are too loud, too shrill. But I see so many progressives and liberals on here spouting fire and lava at Rush and Glen and busting their guts in hatred for them. Do what I do and don't tune in - nothing lost there. So, what's up? Free speech doesn't mean I have to listen to it!!
