On the other hand, Jindal, his ancestors, and white Americans not only refused to assimiliate, but simply killed native people of North America.
They didn't just colonize but take over and occupy the land that is USA today
That is a historical fact.
"無恥" would be a gross understatement for describing him and whoever support his views.
I wouldn't call Jindal and his supporters "non assimilationist Christians" because they are not Christians in the eyes of God.
