The thing to remember is that Rush is an entertainer providing a service: he delivers a very specific audience to his advertisers.
He does this by saying inflammatory things that excite his listeners, and it’s a wildly successful tactic.
Here he is mocking Michael J Fox
What’s important to remember is that he’s an entertainer, not a journalist. It doesn’t matter if what he says is right or wrong, it only has to be inflammatory. He can say something stupid like, “Canada’s socialized health care is crippling their economy.”
If he’s right it fires up his listeners, and generates more ad revenue. His listeners hate socialized medicine and are happy to hear examples of countries crippled by it. They aren’t about to go fact check him, they are happy to ear him say things that confirm their bias. Happy listeners generate more ad revenue.
But if it turns out he’s wrong, he gets attacked for it. Keep in mind that it wasn’t that he said something conservative, he said something stupid. Well, this is even better, now he’s a victim of the hateful, irritated liberals! And keep in mind his listeners aren’t about to fact check for themselves. This fires up his listeners as they rally in his defense, meaning more ad revenue.
Then, because he is an entertainer not a journalist, he can play it off as a joke. Ha ha, jokes on you for believing he actually knows anything about the Canadian economy. He was just exaggerating to make a point, because he’s an entertainer.
What’s sad, is that his listeners/followers aren’t in on the joke. They believe him when he says things factual, and believe him when he says things that are full of shit.
It’s the perfect system. And a little ironic that it was an Australian that took this to it’s logical conclusion and made an entire 24 hour news network centered around this principle.
