The textbooks do note the help of friendly good Indians. They occasionally admit that the Indians weren't totally savage and beastlike. And they occasionally describe a massacre of Indians with such terms as "unfortunate" or "unsavory." But as you can tell, the overwhelming impression is negative.
To be fair, this isn't much different than the non-Christian textbooks James W. Loewen analyzed in Lies My Teacher Told Me. And I believe these textbooks were published in the mid-1990s. Things may have changed since then. (They may have gotten worse.)
A representative passage
Simpson provides one book's "best statement" on Native land and religion:
Undeveloped, developed...didn't matter
Of course, we know what happened when Europeans encountered the Aztec and Inca empires--full-fledged civilizations as complex and sophisticated as their own. They deemed them decadent, corrupt, pagan, unholy--regular Sodoms and Gomorrahs of sin and depravity. Even though these Indians had developed the land, they had to go too.
You can bet this would've happened in the US and Canada as well. The Europeans didn't care what they found because they were bent on expansion and conquest. If disease wiped out the Indians and left the land unpopulated, great. If the Europeans had to coexist with Indians until they could cheat them and steal their land, no problem. If they encountered massive roadblocks such as the Aztec or Inca empires, they slaughtered the Indians and destroyed their civilizations. All in the name of Christ.
This is why blaming Indian deaths on disease is a dodge. The Europeans killed or enslaved Indians whenever they needed to. Their actions show a genocidal intent regardless of the diseases' effects.
While most Indians died of disease, Europeans committed genocide against the rest of them. This happened before, during, and after the waves of illness. Disease was merely a "provident" tool of the genocidal onslaught. Had millions of Indians not sickened and died, they would've received the same treatment as the Indians of the Caribbean, Central America, and the Andes.
