Actually, Hispanics account for the bulk of the Roman Catholic Church's growth in the U.S. Among white ethnics, I have read numbers are actually declining.
That's an inaccurate statement...it would be called hearsay in court.
The bulk of the growth in some parts of the nation (blue states) may be immigrant-based...but here in the Bible Belt (Texas), the majority of parish growth is coming from Protestant converts.
The demographics refute your claim. Only 1 in 3 Mexicans in America, Mexican-Americans and Americans of Mexican ancestry consider themselves Catholic. I'd also invite you to go to your nearest Catholic church, note the parish record of members, note the local census demographics, and then compare the attendance at the six English masses and the one Spanish mass.
I believe it. Since there are no similiar influxes to the Protestants and the whites are leaving them too their numbers are dropping.
