When a young person develops a view that "the media lie constantly and see you as an enemy if you disagree about any tiny thing", that can bed in and last a long time through someone's life. Once trust is gone like that, how can the media redeem itself with someone?
I think this is going to have very long-reaching consequences, decades into the future. There is a growing, persistent constituency of young people who are richly informed by alternative information sources (youtube, online communities, personal experience) whose first exposure to mainstream media is to learn that they're self-indulgent, lying, moralizing bullies.
This is still going on today. See the recent saga with PewDiePie being slagged as a neo-nazi. His response video has 12M views, a lot of those are 13-16 year olds learning to never trust the media, especially when they call people racist.
It's like when you yourself are involved in something and see it grossly, maliciously misrepresented in media. You lose trust in media that way. Gamergate was basically that happening with thousands of people, because all of them had personal experience with gaming and knew how it actually works.
