but you cannot prove your point in the way you proposed in your post.
That's right I think. Nearly every institution in America has been co-opted by secularists (read atheist):
Most universities, founded by godly men are now actively preaching against God.
Most hospitals, founded by godly men, likewise have been co-opted since the government decided they were taxable - and thus sold off by churches and foundations and given over to secular (godless) business.
Most orphanages have been co-opted by the welfare system... Run by a secular government - And likewise soup kitchens.
And finally, many medical research systems are also secular - having nothing to do with God at all.
MUCH of our sciences, universities, research, welfare, and charity have been turned over to godlessness. And what little difference there is between secular and atheist is hardly arguable, because atheists preferred solution IS government...
...And that, nearly exactly in the image of Russia and China as you mentioned.
