The reliably sensible James Kirchick in the Wall Street Journal:

In 2007, former New York Times Middle East Bureau Chief Chris Hedges published a book called “American Fascists” that compared conservative evangelicals to European brownshirts of the 1920s and 1930s. That same year, CNN’s Christiane Amanpour hosted a three-part series, “God’s Warriors,” that equated Christian (and Jewish) fundamentalists with Muslim extremists.
The comparison between the religious right and Islamic extremists is invariably partisan so as to smear the GOP as being held hostage to forces as dangerous as Hamas or Hezbollah. “Even as the Bush administration denounces and battles Islamic religious zealotry abroad, fundamental Christian zealotry is taking hold here at home,” wrote Stephen Pizzo on the liberal Alternet Web site in 2004. On his popular HBO program, comedian Bill Maher frequently compares murderous Islamists to censorious Christians.
But if the reactions to the death of Tiller mean anything, the “Christian Taliban,” as conservative religious figures are often called, isn’t living up to its namesake. If “Christianists” were anything like actual religious fascists they would applaud Tiller’s murder as a “heroic martyrdom operation” and suborn further mayhem.

You’ll notice, of course, that in the examples Kirchick cites, the people engaging in the intemperate rhetoric aren’t just opportunistic political partisans — it’s the mainstream media, folks from the New York Times, CNN, &c. No surprise, but worth pointing out.
