While at the Wal-Mart recently, I noticed that a lot of our ever-growing Mexican population were there. They tend to go as families. After wandering around a while, I found my wife and commented that the Mexicans sure do have beautiful children. Their straight black hair and dark eyes stand out in this area where blonde and brown hair, blue and grey eyes are common.

Is that paragraph racist? Put it on a scale of 1 to 10, with 10 being horribly racist. Which sentence is the worst or best part?
