It’s all of them. They rely on their audience living in the now and having no memory for details, just for the feeling of outrage.
Tucker, Rogan, whatever: their thing is that their audiences remember only what they are hearing now. If they do a 180° flip on their position, it doesn’t matter if it’s over months, or between shows, just so long as nobody hears them doing it live, then whatever they are spewing now is what they’ve always been saying. We have always been at war with Eurasia. Not only will their audiences not notice a reversed position, not only will they vehemently, even violently argue that whatever they’re saying now is what they’ve always said, they will actively fight you if you try to prove the point.
It’s like an audience of goldfish, only it’s more like an audience of angry piranhas with blood in the water and no object permanence.
And to anyone else who is listening who isn’t already trained in bellyfeelfull goodthink, the continual gaslighting is a happy side effect, as it is in any totalitarian cult.
