I think you're taking it too literally. What I mean is that, as an example, if they say $POLITICAL_FIGURE has said this or that, I will suspect they're taking the words out of context, but I am not going to find and watch the entire video, because I don't have the necessary time and energy to do that.
So you don't even believe Donald Trump is the President of the United States, because you refuse to believe the media when it covered the campaign and election?
I'm going to guess you either don't actually hold this point of view, otherwise you could barely function in society.
