Were these racist remarks naive, ignorant or just plain stupid?

Some remarks made by Colorado State Senator Vicki Marble at a recent committee meeting have caused a furor. The full exchange, so not to take anything out of context, is at the above link, but here is an excerpt:

“When you look at life expectancy, there’s certain problems in the black race. Sickle cell is something that comes up. Diabetes is something that is prevalent in the genetic makeup. Although I gotta say, I’ve never had better BBQ and better chicken and ate better in my life then when you go down south, I mean, I love it. Everybody loves it,” Marble said.

The senator went on to mention ”...the Mexican diet, in Mexico, with all of the fresh vegetables, you go down there and they are much thinner than they are up here, they change their diet. I’ve read studies on that…”

Are these remarks any more or less stereotypical than, say a Black Sambo image, or say, El Frito Bandito
