It has always been reinforced, for better or for worse. The entire pathos, and the entire brand of NASCAR operates under an idealized South that had no place to exist anyway. We're still less then a hundred years removed from MLK being assassinated, black people not having the ability to vote or interact in spaces that were occupied by whites, and where government institutions throughout the South consistently flaunted the ethos and flags of the Confederate forces. In markets like Birmingham, Charlotte and Atlanta, markets that are bedrocks of NASCAR since the very beginning, these dark legacies are still present, and reinforce NASCAR's history.
