You ask any Millennial and they will tell you quick that Sacagawea was the one who really opened up the Western United States rather than those two inept white boys, Lewis and Clark.
Pocahontas also has a near divine status in their eyes. And it was Harriet Tubman who freed the slaves.
You are quite the optimist, I don’t think more than 1% of millennials know “Sacajawea” from a bag of rocks.
