The huge difference between the military and civillian casualties and still the military casualties are being brought up way more often in western countries.
Sure, and yet you only presented the civilian casualties attributable to American military action, yet we know that's only a subset of the picture -consider, for example, the horrendous level of military-on-civilian death in the years immediately following the war, both in South Vietnam, as the NVA exacted retribution on RVN officials and military ( which, btw, sparked a fairly serious refugee wave) and in Cambodia ( we all know what happened there).
Thus, while your statement above makes perfect sense to me, the data you presented supported only a very pointed view; unintentionally or not...
