There were a lot of My Lai’s in Vietnam. Biggest misconception is that it was some kind of fluke. But in a “war” where entire civillian populated areas were designated “free fire zones” where you could kill anything that moves, civillian massacres were the norm. Not every solider did it of course but it was a regular feature of that war.
It is good to recognize brave soldiers that resisted. But we must be respectful enough of those who were murdered to not attempt to rehabilitate the image of America in Vietnam by pretending those resisters were the norm or represented the true spirit of America and what it was aiming for or some such sentimental nationalist nonsense. As the article notes, a My Lai happened every month in Vietnam. Civillian mass murder was an explicit goal and the U.S. was very good at it.
