I think the word that works best is "epiphany," a moment of sudden revelation or insight.
It does explain how people with good intentions CAN be wrong, ALL the time.
I do wonder how 30 years of indoctrination can be undone. As for moments of epiphany . . . if 9/11 wasn't an epiphany, what the heck is it going to take? The Modern Liberals' epiphany lasted just about long enough for them to sing "God Bless America" on the Capitol steps. As soon as they went back inside, their old bad habits took over.
