WHAT PART OF THE STAR SPANGLED BANNER BEING PLAYED OVER THE CHARRED CORPSES OF THE VICTIMS OF A NUCLEAR ATTACK BY AMERICA CAN BE CONSTRUED AS COMPLIMENTARY OR "LOOKING AWESOME"?!?! YOU'RE NOT INTERPRETING OR ENGAGING WITH THE WORK OF FICTION IN FRONT OF YOU, YOU'RE HALLUCINATING AT BEST OR AT WORST ACTIVELY REWRITING THE NARRATIVE TO SUIT YOUR GHOULISH PREFERENCES! THE AUTHOR ISN'T DEAD, YOU MURDERED THE POOR FUCKER! AND FOR WHAT, SO YOUR POOR EGO ISN'T BRUISED AND YOU WON'T NEED TO REFLECT ON WHAT THE STORY IS TRYING TO TELL YOU ABOUT REAL LIFE? YOU'RE BASICALLY ADMITTING THAT SENSELESS MASS DEATH IS COOL YOU FUCKING MONSTER! AAAAAAAAHHHHHHHHHHHHHHHHHHHHHH!!!
