If White Americans were aware of their heritage, they would not apologize for their history, nor would they feel any guilt, whatsoever.
If Black Americans knew of their white ancestry, they would not apologize for their grandfathers.
If Hispanic Americans knew of their conquistador ancestors, they would be proud, not ashamed.
Most Americans are completely unaware of their heritage and have been taught from youth to hate their fathers.
A united people cannot be conquered; they must first be divided, bastardized and set against each other.
