It’s hard not to notice that the Sikh temple killings didn’t generate the kind of media coverage, or the political response, that the Aurora theater shootings did. The Joplin, Mo. mosque torched the next day got less attention still. It’s not terribly reassuring that in Mitt Romney’s Tuesday comments on the Oak Creek tragedy, he repeatedly referred to the “sheik” — not Sikh — community. But that’s nothing compared to the jihad by Republicans like Rep. Michelle Bachmann and Louis Gohmert to demonize Muslim Americans.
