It is VERY hard to prove libel. Near impossible. And that’s a good thing. And if you can’t prove libel against a media source, they have first amendment protections.
Look, EVERY media source has bias. Some try harder than others to scrub it out. My solution has always been to ALWAYS peruse at LEAST two news sources, one on either side of the center-line in bias. And both sources have to have a good reputation for factual reporting.
Note that ‘factual reporting’ is not the same as ‘unbiased’. You can see bias in how certain news sources choose not to cover certain stories, or the use of loaded language and click-baity titles that don’t match the content of the article.
By perusing at least one fact-based source on either side, you are less likely to have stories (or aspects of stories) that you aren’t aware of. Then, when the sources clash, if you’re motivated, you can look into the discrepancy in more detail. Or don’t—- but at least you knew there was a dispute. if you only use one source or only sources on ONE SIDE of the center line, you’ll just not be exposed to stories that are bad for the side you cover.
