At some point that becomes bull ****. There was a very clear and obvious cultural shift in 2004, when young Americans started looking to The Daily Show for news. And when that shift happened, Stewart never said, "No! You shouldn't listen to me, I am just a comedian!"
Instead Stewart embraced that role. He ran with it. He used his position and platform to influence the political discourse in this country. He used the position and platform to criticize politicians and the media. He used the position and platform to write books, critique the cultural and become a voice capable of shaping the dialogue. But he did not say, "Don't listen to me, I'm just a comedian." Instead, he did the opposite...he shaped the dialogue. He used his position and platform to inform and shape the political ideology of an entire generation.
Then around 2006, he started using that position and platform to shape the discourse in a way that is advantageous to his own view point. He would skew facts. He would pull punches when he agreed with someone, ideologically. He would heavily edit interviews to destroy those with whom he disagreed. He would shape the discussion as he saw fit, for an entire generation, while showing no restraint or neutrality and exercising no accountability. This is the very thing he LITERALLY wrote a book criticizing the media for. He claimed they have a responsibility and accountability. He embraced the influence that came with being one of them, but when it came time to embrace the same responsibility that he DEMANDED that they embrace, he hid behind the easy guise of, "Well I'm just a comedian."
But that excuse really doesn't hold up. "Just a comedian," does not get to interview the President of the United States more than any other pundit. "Just a comedian," doesn't get to sit down with Senators and leaders of industry and presidential candidates. "Just a comedian," does not organize and lead political marches on DC. Stewart became a political/media figure. And this was a role that he actively embraced when shaping the dialogue and wielding the influence. He embraced the role and influence all while criticizing others in that role, with similar influence, for not holding it with accountability and responsibility. Yet when it came time to have the accountability and responsibility that comes with being a political/media figure that can exert influence and shape the dialogue, he shrank away and said, "I'm just a comedian." That is hypocrisy, plain and simple.
