Foots, back then, Catholics from Germany, Ireland, and Italy were victimized by others in this country, and United into communities that brought out the best in humanity. Same thing with Muslims after 9-11. Anger is still aimed at them. Living in Alabama I know two doctors who are muslim, one of which routinely participates in charity events, and there are two mosques that bring out the best in humanity as well in my area, 50 mile radius.
The US was not founded on Christian values, some states were, but not all. Those that say the United States is a Christian nation, are just as delusional as ISIS and the KKK.
