No, Ace, I was thinking more in terms of religions from islands where they mingle voodoo and black-magic with Christianity, or from nations that export islam, the 'sacred cow' or paganism and atheism to us.
Where people get the notion that just because folks slither unnoticed over here from Central and South America that that somehow guarantees they are good Catholics who practice the faith of their ancestors, is a mystery to me. In fact, a great many of these illegals become members of Latino gangs, or become criminals. One-third of all California prison inmates are originally from south of the border.
The truth is that not too many devout Christians would begin a new life in a country which they reside in illegally, drive uninsured and unregistered cars, and in general take advantage of every benefit of the U.S. government without giving something back, (as in, ahem, paying taxes). This way of life actually flies in the face of the the teachings of the Holy, Roman, Catholic and Apostolic Church which you mentioned.
Considering that one child in four dies sacrificed to Moloch in this country maybe criticizing voodoo practitioners strikes one as a bit, well, disingenuous.
