July 4 is a celebration of the victory of the Union over Confederate terrorist slavers and sex traffickers at Gettysburg.
The cartoon contaminates the honor of 365 thousand Union war dead by mixing the rebel dead with them. Union is paid in full.
The South's 290,000 dead, like their Confederate currency has no value as they were fighting to for the worst of all causes. Their bill is yet to be paid. With interest due to vile treatment of black people for more than a hundred years after the signing of the deal Lee made with Grant at Appomattox Courthouse.
The right's obsession with Cortez is adorable.
