At first they were WASPs (White Anglo Saxon Protestants) Then their numbers dwindled so now they're just Christians, no longer protesting agianst the Roman Catholics, who at the time were still having lots of babies...
Soon they'll have to drop "Christian" and consider "Monotheist"... they're kind of getting there with their Jewish allies... but the real baby factories are another group of Monotheists, the teeming masses of Islam... and some of them are white enough, but some aren't.....
It really is a big demographic problem....
Oh dear, how are they going to save America and the terrestrial globe? I wonder....
