You know, it makes sense that gangstas and rednecks are similar. If you look at history, you can see why they're so similar. They're basically descended from Southern working class culture, which has always been multiracial. It's just that a lot of African-Americans had to leave the South in the first half of the 20th century because the segregation and the racist policies of the region forced them into other parts of the country to find work. So gang bangers are really just citified hillbillies with baggier clothes IMO.
In fact, the two groups actually share a common cultural ancestor in the English Lowlanders. Both groups' distinctive dialects are derived from Elizabethan English.
