Clear Channel's Rush Limbaugh or Glenn Beck aren't a different recipe of cornbread. Nor is WOAI's Joe Pags for that matter. Those guys pump/pumped out lies and conspiracies. Political banter is far afield from straight up BS paraded as a different POV. And quite frankly, you equating them underscores how dangerous it is, because its so ubiquitous now, you don't even recognize how destabilizing it is.
Nothing matters when we collectively lose our basis in a universal undisputed set of facts. When facts become damned, there is no keeping people together. It's precisely why you have the right wing already starting to pine for a "national divorce" (see MTG's tweet) or worse yet, civil separation by any means necessary (see twitter on pretty much any day). Those local talk show hosts across this country spew BS (like Democratic politicians are groomers/pedophiles and have secret lairs where they perform said acts, want your child to have gender reassignment surgery at will, are in cahoots with dark forces, want undo ented workers voting, etc, etc, etc.) from their microphones daily.
And a bunch of that local radio show amplification of that filth originated with stations like WOAI, then Clear Channel where abominations like Rush gained national reach with their voluminous mouth diarrhea.
One last thing, that stuff was far from being just 3AM talking points. In fact that type of insanity permeated our national discourse and metastasized into being the predominant "talking points" of the Republican base voter.
