You and Pew are wrong in your conclusions. Spinning the data doesn't change the facts. Although many Catholics at various times of their lives do stray from the Church the estrangement is rarely permanent.
Regardless of the beliefs of your Church that in many ways parallel those of the German Protestant (Nazi) Church Hispanic, Indian, Filipino, Polish, Irish, Vietnamese, and Slavic Catholic immigrants are fully human and do count in the official numbers.
lol. Pew and countless other studies and our own lying eyes say otherwise.
If immigration laws on the southern border of the U.S. were enforced, the RCC would dwindle considerably.
