How is it that elected politicians are incapable of crafting better rhetorical arguments? I'm guessing it is because the average American now has an IQ of about 75.
It's true that African Americans and Hispanics have sickle-cell at a much higher rates than other ethnic groups. It's genetics, not racism. And true, her wording could be a lot more better and focus on the culture of unhealthy food in the south as a whole contributing to obesity and diabetes. Still, I don't think this is the equivelent of yelling "NIGGER NIGGER NIGGER" on a youtube post or something. A little ignorant, yes, but not mean spirited, I don't believe.
Though this is largely because of the poverty which has been ingrained over many centuries. Shit tastes better deep fried and slathered in hot sauce or BBQ or brown sugar.
