A Christian country. You realize, don't you, that the only people who still vote Republican are extremely stupid racists and mostly very, very old? Non-white people have always lived on this land. In fact, non-white people were here long before you European Christians showed up to rape the people, steal the land, and build one of the most evil empires that has ever stained the face of the planet.
The better angels of the US's nature only manifested after the Civil War when slaves were freed and then more importantly, after WWII (which the US won thanks in large part to non-white non-Christians) when voting rights and civil rights were expanded and the territorial claims took their independence.
In fact, the US has been most evil when it has been most white. The best thing that will ever happen to this country will be white people slipping into the minority and being unceremoniously stripped of their unearned privilege and power.
