The more recent statement, while dumb and sheltered (no LA blacks were singing the blues in the 50's and 60's? That's metaphorically and litterally incorrect as hell), wasn't overtly racist in a hateful and n-word overt kind of way. Duck Dynasty is a white hot mega-franchise that isn't likely to be sunk by these gaffes.
"Blacks were more godly before the Civil Rights movement" is a pretty damn racist statement...
Well, that's not exactly what he said. You and I both know that's what he implied, but the way he said it doesn't create nearly the same soundbite necessary to create a media firestorm. We both know style often trumps substance.
