As to centrism, I'm not sure Rogan has enough of a coherent ideology to even call him a centrist.
But people who watch Fox News - for the most part - are watching for actual news. They often believe it. They aren't questioning the 'facts'. It isn't even as fake as Tabloids saying "I had an alien baby!".
While Fox is as trustworthy as 'The Onion', 'The Onion' openly states it is satire: Fox News is still claiming news and facts.
Things have changed. Dramatically. And for the worse. Anything and everything is considered news. Relevance and important are not longer relevant; the reporting shamelessly anti-objective. Anyone can at this point call themselves a journalist, without any understanding of the actions and ethics such a title entails. Axe-grinding and whistle-drowning are all too common.
The bottom line: A healthy, proper and transparent Fourth Estate matters. I can't speak for the rest of the world but in the USA the Fourth Estate is in the ICU, and has been for some time now. This is not a diagnosis that is new since Jan 2017.
It legitimately comes down to however you frame a question to someone.
