Rush Limbaugh: "We Need Segregated Buses"

Referring to an incident in which a white student was beaten by black students on a school bus, a caller to Rush Limbaugh's radio show stated that the local police concluded that the attack did not appear to be racially motivated. Limbaugh's response:
"I think the guy's wrong. I think not only was it racism, it was justifiable racism. I mean, that's the lesson we're being taught here today. Kid shouldn't have been on the bus anyway. We need segregated buses--it was invading space and stuff. This is Obama's America."

And this:

"If homosexuality being inborn is what makes it acceptable, why does racism being inborn not make racism acceptable? I'm sorry--I mean, this is the way my mind works. But apparently now we don't choose racism, we are just racists. We are born that way. We don't choose it. So shouldn't it be acceptable, excuse--this is according to the way the left thinks about things."
