I think most of the people judging Breitbart are doing so through the prism of their political biases. Many probably would not be decrying the lack of context in a video that made their political enemies look bad, for example.
I have to say I admired the guy for his balls, his enthusiasm, and his ability to take on degenerate institutions and special interests. He wasn't perfect by any means, but he's been vindicated numerous times after withering accusations of lying (e.g., Anthony Wiener). He put up a $100,000 reward for anyone who could provide video evidence of racial epithets being hurled by the Tea Party at black congressmen, and in an era of ubiquitous flipcams and camera phones, no one was able to claim it.
He was flawed, wrote rambling articles, and did some collateral damage to people who didn't really deserve it in his takedowns. But he also fought like hell against anti-gay bigotry in the GOP and hypocrisy and elitism on the left and in the non-FOX media, and shone a much-needed light on the festering underbelly of certain special interests.
I'd be all for more Breitbarts on the left and right, because there's plenty of bullshit on both sides.
