I never thought about it before but Full Metal Jacket is kind of retrograde the way it portrays the guy who blasted his CO as a sobbing incompetent moron. In reality there was a lot of resistance and direct murder of COs by GIs during the Vietnam War, but it wasn’t done by antisocial mouth-breathing idiots but principled resistors.

Well, Gomer Pyle is not supposed to be a depiction of a "principled resistor". He's supposed to be a depiction of a guy who is obviously mentally disabled, but got pushed through medical examination anyways due to lowering recruitment standards. As I understand that was also a hot-button issue at the time.

That said, I would personally prefer that you did not speak so frankly on your opinions regarding Mr. Pyle. Comparison with the character is actually one of the ways people where I live used to use to try to get at me.
