True Rednecks and Southeners have real class and correct manners. They know that is impolite to make fun of a group to which you yourself do not belong. Therefore, no black jokes if you are white, but it is also wrong for black people to make white jokes. Ignorant elitists make fun of rednecks all of the time, and never turn the spotlight on themselves. They have no class.
Foxworthy can make fun of Rednecks because he IS one. We can laugh at ourselves, but liberals, who swim in a sea of irony, never do.
