Americans who criticize secular government in Europe --- when your country finally tears itself asunder over faith and denominational division, and your streets run red with the blood of martyrs on all sides, maybe then you'll see the merits of keeping religion out of politics.
Europe's religious divisions tore the continent apart for countless centuries. Atrocity followed atrocity as one "righteous" group attempted to lord it over the other. America seems to still be in that stage where religion is a necessity in good governance - Europe was there many hundreds of years ago and we have since abandoned that notion (something which america frequently chastises us for). As the post says, just you wait America, when the storm hits you and your growing numbers of denominations and ideas, maybe the killings and turmoil will make you see our point of view.
