What a great BS. Glory to the peaceful and pious settlers, probably blessed by God as well, isn't it? they just gave those bloody red bastards what they deserved.And this right here is the problem. "All wrong or all right." You can only see black and white. This explains how you can call the gas chamber "humane" compared to beatings, rapes, whippings, and kidnappings - crimes that have been committed by members of every civilization and culture that ever adorned this planet, including the Native Americans. In your "all wrong or all right" world, everybody is a Nazi.
But I'll sum it up anyway. The Nazis committed genocide. The Americans did not. The Nazis took densely populated land by force when there were peaceful, legal means available for their people to spread out. The Americans and colonists tried to spread out peacefully into unpopulated land that was governed by the law of the jungle, and reacted with force when they were savagely attacked.
"Riding through dustclouds and barren wastes
Galloping hard on the plains
Chasing the redskins back to their holes
Fighting them at their own game
Murder for freedom the stab in the back
Women and children and cowards attack".
What do you like us to tell next? That it was good to hold the blacks in slavery, because..... I don't know, probably you have an flimsy excuse for it, too!?
