Stan Marsh represents the average kid in America since he always gets pressured into situations that spin out of control(Episode F'ed in the A).
He basically says what everyday Americans are thinking in contraversial episodes thus he always ends up making up the moral at the end of the episode.
Stan Marsh: Ok. Good.
Randy: I know i can't stop you from doing it so all i can say is... Give them Hell Son... Give them Hell.
Stan: God Damnit!
