Breitbart is in the business of generating traffic and selling clicks so they have a tendency to sensationalize and generate stories in ways that maximize that. They have to keep people wound up to keep them interested and clicking. I think of them as the HuffPo of the right.
They do have some good reporting at times but other times, their headlines can be misleading. I always keep in mind that BB is first and foremost, a business.
Not a stretch, in view of the fact that Andrew Breitbart was one of Arianna Huffington's right hand men in setting up and launching HuffPo.
