Well, redneck brawls happen in other colors too.
They certainly weren't rednecks to start with, they were halfwits.
Also 20% of the population and 90% of the ridiculous restaurant fights, assaults and acting like assholes in public. I don't have a link for this but it is actually common knowledge much like I don't need to have a link to post proving the Sun is big and hot.
Facts are facts not racism. I wish people could get this through their heads and quit making excuses for their foul and thuggish behavior.
