I think I am missing

I think I am missing something
I am unfamiliar with Pat Buchanan’s politics, but I know he is Catholic. I heard him speak a few times, and I thought he made some sense. My personal favourite Catholic presidential hopeful was Alan Keyes, however.
The other day I got the Roman Catholic Books catalog in the mail. I usually enjoy flipping through it. I stopped short at an advertisement for Pat Buchanan’s book Death of the West. I have not read the book, so I am not offering a critique. The ad did scare me a bit. Am I overreacting, or missing something?

Collapsing birth rates and native populations… out-of-control immigration… a process of “de-Christianization”
With electrifying prose and massive documentation, Buchanan reveals:
* How collapsing birth rates in Western nations, coupled with skyrocketing birth rates among Muslims, Asians and other Third World peoples will soon cause cataclysmic shifts in world power
* How uncontrolled immigration is changing the composition of the U.S. and European nations in ways that threaten their survival
* How our cultural institutions have been deliberately and systematically undermining the foundation beliefs and traditions of American and Western civilization for years
* Why aging populations will force developed nations to choose between mass immigration and mass euthanasia
* Why the Christian majority in America was routed — with help from its own clergy
* Why young women are not having children in America and Europe
* Empty churches, full mosques: the long-term implications for the post-Christian West
* Why immigrants from Mexico will never assimilate
* Why the GOP may be history by 2010
* Six terrible consequences of the overthrow of the moral order
* Five ways you can enlist now in the battle to preserve Christian America
* The single most important cause for 21st-century conservatives
* The “absolute correlation” between religious faith and large families — and between loss of faith and population decline
* Empty doomsaying? “The Death of the West is not a prediction of what is going to happen,” Buchanan clarifies, “it is a depiction of what is happening now. First World Nations are dying. They face a mortal crisis, not because of something happening in the Third World, but because of what is not happening at home and in the homes of the First World.”

Emphasis added.Now, I understand how there are problems that are the decline of Christianity, such as birth control, but what’s this whole native populations deal? Isn’t Christianity for all? I am lost here, or am I being overly liberal/sensitive. I personally think that the decline of Christianity has more to do with bad formation then immigrants, but that is just my opinion.
