The left has its own biases, but to equate it with the Fox News/Breitbart bubble is dishonest. To take science as an example, the left has its own set of denialists (ex: anti-vaccers, anti-GMO), but the left has plenty of people who push back against such science denialism. The Fox News/Breitbart bubble doesn't have any such checking mechanism. There's a reason why creationism is popular in the US.
