I know why. I grew up in Appalachia and it is really one of the most "old-timey" Christian areas of the country. The notion that the "Bible Belt" somehow increases the amount of STDs sure as hell doesn't explain Utah. It is a scientific and demographic fact, that can be looked up using CDC data, that some minorities have greater amounts of STDs. We can resist pointing out the 1000 pound elephant in the corner all we want, but he is still taking up a damn lot of space.
