I read somewhere that the majority of Hispanic Americans are protestants. The independent / loosely attached charismatic churches seem to be the fastest growing demographic here in the States. Like home schooling, there's a lot of stuff going on "under the radar" of the cultural elites -- a lot of encouraging stuff!
wish I could cite the book which indicated that immigrants to America are disproporitonately likely to be Christian, and if Christian, disproprotionately likely to be Protestant, than their country of origin.
