Figuring this shit out is a lot of work to be honest. Even a truthful source can be misleading as hell by omitting important context. Just like for hardware review, or video game review, or whatever, I try to find someone whose reporting omit nothing on some stuff I heavily researched (it's rare), and only then I feel comfortable weighting in their report on the stuff I know less about.
On the other hand, a lot of people just eat everything up from some random source they grew up with because the alternative is a lot of work, mentally and emotionally.
That being said, there is a certain point where listening to those people's opinions stop being fruitful. Hence, I don't really care about any extremist views in places like Lemmy.
