Faith in the one true God of this world is the only force that has kept mankind from rabid degeneracy. To deny that is irrational, illogical, and false.
I didn’t realize the Japanese, Chinese, Indians, etc. where all Christian... or even monotheistic.
There are many countries where "faith in the one true God of this world" is much stronger than in America. With few exceptions, these countries are corrupt and tyrannical hell-holes. Countries with no faith in anything above human intellect (e.g., socialist bloc) are equally hellish.
What the hellish countries have in common is that their cultures are dominated by mass movements, whether secular or religious.
What the non-hellish countries have in common is faith in something higher than human intellect (whether it's God, Tao, natural law, etc.), but not to the point that such faith gets organized into mass movements.
I believe that America is being destroyed by two complementary forces: People who have discovered they can vote themselves other people's money and politicians who pander to them. These politicians say "Vote for me and I'll take money away from other people and give it to you." When there's no "virtue in the people," it is impossible to compete with this platform.
If organized religions want to claim some relationship with the "true religion" that the Founders say is necessary for a governmet of free people, they need to be a lot more explicit about promoting the sort of morality that would counter the urge to vote oneself other people's money.
