Fox News and other conservatives are busy attacking Attorney General Eric Holder for assuring the public that law enforcement will not tolerate any acts of violence or discrimination in the wake of the Boston Marathon terror attack. But their latest feigned outrage ignores that hate crimes against Muslims are a very real concern.

Fox News anchor Megyn Kelly covered the story on the April 30 edition of America Live, hosting Fox contributor Michelle Malkin, who mocked the “phantom threats of hate crime epidemics that have never happened.” (This was the second straight day Kelly had devoted a segment to expressing outrage about Holder's common sense comments.)

Other conservatives lashed out at Holder for his vow to defend religious minorities in America.

Fox's weird attempt to push back against Holder's pledge fit nicely into Fox's frequently anti-Muslim programming. It also highlighted how little interest Fox has in the larger issue of anti-Muslim violence.

I noted last week how Fox News remains largely blind to acts of right-wing extremist terror and political violence because that storyline doesn't fit into the cable channel's preferred narrative about Muslim terrorists, or Fox's eagerness to assign collective blame onto the Muslim-American community.

And when it comes to Muslim houses of worship, Fox's main concern in recent years has been to demonize those trying to build new Islamic centers in the U.S., and also how to bug them. That lack of attention and concern may explain the network's outraged response to Holder's comments. There is clearly cause for concern, though.

From Salon, August 14, 2012, recounting a string of seven attacks that occurred within an 11-day span:

Teens were arrested on hate crime charges for taunting worshipers by throwing eggs and oranges and shooting bb pellets at a mosque in Hayward, Calif. Vandals defaced the Grand Mosque of Oklahoma City with paintballs, and, in an especially malicious incident, women hurled pig legs at a mosque site in Ontario, Calif., while people were leaving the temporary prayer space.

According to FBI crime statistics, the number of anti-Muslim hate crimes fell from 481 in 2001 to 107 in 2009. In 2011 though, the number of incidents jumped back up to 157.

The good news is that according to press reports there have not been many retaliatory acts since the Boston bombing. But that doesn't mean Holder's comments were out of line. And that doesn't mean mosques haven't been regular targets in recent years. For Kelly to dub Holder's comments “controversial” just shows how little attention Fox has paid to acts of religious violence and vandalism.

Here's a recent timeline:
