"Everybody stop the colonial exploitation for a minute and scrunch up!"
I was just mad at how the South was pushing all of its excess money into the major cities like Saigon. The South Vietnamese government seemed to ignore small towns and villages, like mine. Ngo Dinh Diem (the leader of South Vietnam at the time) even took away our farms and put them under the control of a single rich guy who'd supported the French in World War II. This happened all over South Vietnam and was called "land reform," rather than the far more accurate "serious, deep, and exploratory boning."
The French, who had controlled Vietnam since the 1800s, always saw the locals as "lower," and we never forgave them for refusing to give us independence. Ho Chi Minh was snubbed twice, and after the second time he reacted. My uncle also wanted independence and would do anything, including support Communism, to get it.

Banner politics don't really leave a lot of space for nuance.
Once the fighting started, a lot of people died, well over a million on our side alone. For the war to continue, a constant stream of new fighters had to join up, and they didn't have the benefit of such luxuries as "functional equipment" or "the slightest idea what to do." Over 90 percent of these new recruits were teenagers or younger. Many of them weren't even particularly invested in the "cause" itself. Supporting Communism or the dream of a united Vietnam was less a motivator than wanting revenge for the death of a parent, loved one, or child. The Viet Cong (literally: the National Liberation Front or just "the front") were just a means for securing that revenge.
