Lincoln came out as a great man in spite of himself, but history is not like the 6th grade history books, on many subjects, not just Lincoln. Those McGraw hill books are pre read and either redacted or changed to suit the current government before they ever go to print. For Christs sake, My sons 11th grade history book had 2 short paragraphs on the Viet Nam war That summed it up like this: The Viet Nam war was an unpopular war fought in southeast asia where 56,000 Americans died, end of story! And you know some light filler material like, almost a million Vietnamese died when the war started by the Viet cong attacking one of our ships in the gulf of Tonkin, Pure bullshit.
