Coming from NYC, Staten Island in particular, can’t say that i know anyone well who is anything but Roman Catholic.
One FReeper was nice enough to break down a number of denominations and their beliefs, but my memory stinks.
Besides, I have enough on my plate figuring out what the heck is going on with my group right now.
Plenty of non-Catholics, indeed non-religious white people in Manhattan and the gentrified neighborhoods in Brooklyn. Staten Island, as you know, is its own little world.
