Serbia and Russia are probably the two least degenerate societies in Europe and this is due to the power of Orthodoxy.
I'm sure there's much variance by region, e.g. Catholics from here in South La. (I was baptized, but haven't practiced since childhood) are more like other Southerners than New Yorkers, but:

And that's just the unimportant stuff, Catholics tend to lead charge for more immigration (Lutherans, Mormons, etc. are often as bad, but have less sway).
I wasn't aware Mormons supported immigration to a higher degree. Today it is important to distinguish Polish/German/Irish/Italian Catholics from Latin American Catholics who naturally favor more Mesoamerican immigration than the average Catholic.
White Catholic and White Protestant rivalries have cooled down politically as they cooperate across denominational lines on issues like abortion on conservative vs liberal lines, urban "Ethnocatholic" enclaves have been severely diminished by transethnic mixture into a homogeneous White American blob, that included the forcible transfer and promotion of Southern Negroids into Ethnocatholic neighbourhoods "on the south side of Chicago" much discussed by E Michael Jones, and into the rural and Western areas, the Irish had fewer Irishmen to marry anyway. Irish Boston remains a Blue stronghold but "Irishmen" don't fully exist out here in the rural west. I think San Francisco is rather Italian-Irish.
I think Salt Lake City is already 25% "minority" due to LDS mission efforts, and is a sanctuary city
The Lutherans are even more insane, i doubt they convert any of the people they resettle (often Muslims like my Iraqi Kurd in-law). Here's some news on the relationship between the traitor churches https://refugeeresettlementwatch.wo...etting-on-the-refugee-resettlement-bandwagon/
