Anything that makes the devil shriek is good

I am behind on my reading. I am reading a post in David Warren's "anti-blog" about the government shutdown in the United States. David writes,

The histrionic reception in gliberal media is also to be celebrated. Anything that makes the devil shriek is good, & the very foulness of their language assures us that the news has not been faked.

Verily: the demonic power, alike of journalists & terrorists, depends upon the human disposition to panic. Refuse to panic, & they are suddenly enfeebled. “Fear not,” as our Lord saith.
