None of that has anything to do with America and Americans, that is some old European stuff, Americans never thought much of those people and all their brutality and rivalries and just overall weirdness.
Of course it does. Anti-Catholicism has been a continuing theme in American politics. During its heyday, the KKK was far more militant against Catholics and Jews than against blacks. Thats when Oregon tried to shut down Catholic schools in the state and force all children to attend public schools. And of course, you have never heard of the Blaine Amendment.
I wonder if such folks would say Christianity is some old Asian/Middle Eastern stuff
No, wait, non-Apostolics do -- like the ECUSA, ELCA, PCUSA etc. congratulations ansell...
