Actually, it isn’t a given that the illegals who are given amnesty will be Catholic. A lot of them end up in Pentecostal churches, a phenomenon I have personally witnessed here in Northern Virginia.
I don’t know if it’s only in Virginia (I’m in Richmond), but I am hispanic and there are alot of small Spanish-speaking Pentecostal store-front type churches. Just in knowing the community here, I’d daresay there are tons more attending the small churches. This topic comes up alot in the bodegas and at the soccer fields. Those little churches are like tiny illegal hotbeds.
I remember reading... and citing on FR... a poll which found that only 38% of Hispanics residing in the U.S. were Catholics, compared to 24% of the general population.
