I do not dispute your statistics; I am however a Christian man and as such I know that culture is made or destroyed not by the statistical units but by certain people lead by the Holy Spirit, whose number is few. In the Catholic Church, there is a revival in sufficient numbers that I was able to find a spiritual home both in California and now in Kansas City Metro. It just hasn’t reached all of the bishops yet.
I don’t think that you realize the purpose of the 1965 Immigration Act, it was to erase America and American culture, and to replace it with exotic third world foreigners who didn’t know, and do not care how we had built the greatest nation in the world.
Protestants don’t vote democrat, they only voted democrat in 1932, 1936, and 1964, the left had to replace the American Protestant voters, or they would never be able to survive, so they changed out immigration laws in 1965.
Immigration means the democrats take it all and the past disappears.
