Or maybe you have too much trust in those sources? I don't find Greenwald credible, for example.

This is just it - most people criticize the media have a clear political agenda, it oozes out of them. In this case, it immediately goes to Trump and Russia, almost instantly, almost as if it's a campaign. It misleads by saying "we don't have direct evidence of this, therefore it must not have happened." The two articles linked are not convincing.

Often times people complain about the mainstream media and then post their own media, without convincing me why I should trust this media over any other media.
