Shep Smith is a tiny point of light in the bleak night that is Fox News. TPM finds him calling out the birthers and other wackos who email him. Unfortunately, Fox is a major factor in giving credibility to most of these extremists. Some version of much of the crackpot hate speech these people feed on is regularly featured on Fox - and regularly spouted by the usual Republican demagogues.
The recent murder of the security guard at the Holocaust Museum and of Dr. Tiller are natural sequellae of the lies regularly spouted by Gingrich, O'Reilly, Hannity, Malkin, the Buchanans and ilk. Those who have given them their platforms deserve to be held accountable.
