Ohh man, this is GOLD.
Some woman at a rally said, "I'm afraid of Obama because he is an Arab."
McCain then responded by saying, "No, no mam. Obama is not an Arab. He's a good man. He's, he's not [an arab]"
Dissecting this response is alarming. I mean, McCain quickly denies that Obama is an Arab, but he doesn't say anything to quell the fears that Arabs are bad people. They could throw in any noun in the place of Arab, and it would sound the same.
"Obama is not a Nazi."
"Obama is not Osama Bin Laden."
"Obama is not Hannibal Lector."
"Obama is not an Arab."
You can see the way some people here think nowdays.
