In response to the reasonably rational Fox News' Shephard Smith suggesting that the Holocaust museum shooting and his own recent mail are evidence of a growing and scary right-wing extremism, Media Matters notes, he has been pummelled by increasingly hysterical conservatives. As Paul Krugman notes here, the shrillness of these "all-American lunatics" and their only moderately more coherent cohorts alarms.
"They were warning us for a reason," notes Smith about an earlier DHS report about the rise of rightwing extremists. "It was a warning to us all.
And it appears now that they were right."
