>>5136270Donglover represents America.
Donglover is wearing confederate army pants.
He is dancing with a few upper-class black teens to distract the audience from the carnage and murder happening in the background.
Gospel churches are pieces of black culture that white suburban Americans adore, and Donglover dances with them until he gets tired, and then he kills them.
Notice how the two guns he used get treated after people were murdered, as opposed to how the guitarist black man got treated after his execution.
Last scene is open interpretation. In my opinion, since Donglover represents America, the people chasing him are revolting during his darkest days.
