Rush Limbaugh has never hidden his bigoted beliefs, and on Tuesday he went on a racist rant about a highly disturbing incident on a school bus where a black student attacked a white student while other children cheered on. As Ben Frumin at TPM puts it, Limbaugh acts as though this is all the fault of President Obama:

Rush Limbaugh weighed in today on this video of a 17-year-old white Illinois student beaten up by two black classmates. Shockingly, his analysis doesn't reveal an even-handed understanding of our country's complicated racial history. In fact, not only does Limbaugh imply that this high school scuffle is racially-motivated -- but that somehow, it's the fault of President Obama.

"In Obama's America, the white kids now get beat up with the black kids cheering, 'Yay, right on, right on, right on, right on," Limbaugh said. I wonder if Obama's going to come to come to the defense of the assailants the way he did his friend Skip Gates up there at Harvard." Read on...

At some point, the hatred coming from the right and their mouthpieces on the radio will hit critical mass in this country. I'm all for free speech, but entertainers like Rush and Glenn Beck are walking perilously close to "yelling fire in a movie theater."
