I don't know if they could do a better presentation of missing the forest for a single tree. PewDiePie could have personal views that would make David Duke go "well, hold on now, that seems quite bigoted young chap" and from what I've ever watched of him you wouldn't know it from the bulk of his content which involves screeching at video games. He's not normalizing anything except being fucking annoying most of the time. Yet he's some kind of menace that the enlightened NeoGAF.com user can pick up on all the code words that elaborate his worldview that he secretly transmits to his viewers?
The comparison to JonTron is odd. That parrot got "caught" not in his own videos but in an interview he was doing elsewhere and on twitter. (I think? I know most of these people via dunkey, etc. and their SCANDALS rather than their own content.) And had a more elaborate worldview he was eager to share beyond what's effectively cursing or in the earlier case with PDP, low bar black humor. (Compare PDP's holocaust jokes that were so terrible, for example, to the H3H3 story about meeting at the Holocaust Museum and his joke that he approached her in the Museum with the opening line: "they had it coming don't you think?")
If you go to the mainstream news, or make this a moral panic, it's going to backfire. People are going to be like "what? That's fine for my stupid kids to watch."
Meanwhile, there are all sorts of channels where the bigots aren't playing video games or doing skits in which they sometimes slip up and say something bigoted but instead spreading truth about gay frogs or WTC7 or chemtrails or the person who believes in the development and protection of a Jewish nation plot by Bankers to slaughters all Christians to established an Atheist Caliphate.
And perhaps even more frightening, there's stuff like this on YouTube and the primetime TV news isn't covering it:
