You might add that Krauthammer also emphasized that that sort of thing was disappearing, what with government support of religious non-profits helping poor people etc. I don't know if I'd have agreed with him on that, but he emphasized it. Which is why your assertion that Krauthammer "hit the nail on the head" about some assault on religion surprised me.
He did say that, albeit I disagree. We can't read the Bible in a positive sense in schools -- even if it is part of a personal activities day. Teachers take a chance if they teach that the Declaration of Independence means what it says about a Creator.
A judge can't put up a display of the 10 Commandments in his courtroom, although if he wanted to set aside part of it for an exhibit of cutting-edge art, I doubt a challenge on First Amendment grounds would be accepted.
