BD... these accusations you've linked mostly revolve around the defense of Anthony Weiner and Shirley Sherrod. Honest people, both.
The worst you could accuse Breitbart of in my mind is creative editing of some of the hidden camera stuff he did. And in all cases of when he was accused of that, he released the full, uncut video afterwards.
Let's face it, Breitbart played dirty but he played for our side and the left can't handle a taste of their own medicine. If Breitbart had been a liberal and had gotten crap on the Koch brothers or ExxonMobile or something but used the same tactics, all of our resident liberals and "centrists" would be telling us how great he is.
