Forty years of many (most?) schools teaching that America is an oppressor nation has left us with two generations who believe it.
"Freedom is never more than one generation away from extinction." "We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free."
Ronald Reagan.
