I’m sceptical, the only difference between news sources is how your bias gets confirmed, or not.
This is right-wing propaganda you're regurgitating here. It's the whole foundation of things like FoxNews: claim all news is biased, and poor conservatives are not being represented, and then make a conservative news outlet and claim it's fair because "all sources are biased."
Sure, it's true, there is no such thing as completely unbiased, which is why this has a grain of truth to it. All the best lies are rooted in some reality. But there are sources that are far more accurate and less biased than others. "Well, they're all biased" is just more of the "all sides are the same!" BS.
