What a difference a name makes? Mohammed v. Loughner

The 19-year old Oregon male versus the 22-year old Arizona male.  Same age group.  One had plans to kill, but was apprehended before the act was carried out.  The other shoots at quite a few, and kills.
But, the only terrorist is the Oregonian?  All because of the differences in skin color, name, and religion?
Here is Peter Beinart:

Had the shooters’ name been Abdul Mohammed, you’d be hearing the familiar drumbeat about the need for profiling and the pathologies of Islam. But since his name was Jared Lee Loughner, he gets called “mentally unstable”; the word “terrorist” rarely comes up. When are we going to acknowledge that good old-fashioned white Americans are every bit as capable of killing civilians for a political cause as people with brown skin who pray to Allah? There’s a tradition here. Historically, American elites, especially conservative American elites, have tended to reserve the term “terrorism” for political violence committed by foreigners.
