This is pretty much my view too. The Duran are a good example, so are the Grayzone, or Pepe Escobar even. They each have their uses where they offer good news or analysis, but they also have instances where they can turn into utter garbage, for instance when it comes to topics like vaccines or socially progressive views on gender. It is what it is. You just have to learn to “eat around the bad spot”. Take what is useful to you and discard what is not.
If we only ever consumed media from sources that we 100% agree with, firstly we would not have any media to consume at all because there is always something to disagree over even with other leftists, and secondly we would be living in a very small echo chamber. You just have to trust that your own ideological convictions are strong enough to not be swayed by stupid, unscientific, reactionary nonsense. And if you are unsure on something you can always come back here and discuss with your comrades.
