"she throws darts at the behavior of 18th century pioneers"
Mr. Austin, I think you mean the 19th Century.

Col. Chivington attacked an Indian camp when the warriors were gone, leaving only the old, the women, and the children. He attacked a camp flying the US flag as a flag of truce. Even Congress was appalled.

But John Evans and other Colorado pioneers, like most people, are far more complex individuals, comprised of equal parts good and evil.
Rather than rename every mountain and demolish every monument, wouldn't it be better to use our schools to discuss American history in an equally complex manner, and show that the people who came before us and made this country what it is today, for the most part were not caricatures, were neither fully saints nor fully sinners, but human beings?
As one example,
Abraham Lincoln held the country together during the Civil War Between the States -- and also suspended habeas corpus in Mayland to prevent the state legislature from voting to secede.
