I think I might argue that that is part of the problem, and that the solution is more along the lines of my reply at #16.
But even if we sidestep that whole argument, the bottom line is that young [European] people [like the poor French girl in question] just aren't reading any of that stuff whatsoever.
Growing up Catholic, and even going to Catholic school until college, I learned more about Christianity in the 3 months I went to (Protestant) Bible study while I was deployed to Kuwait than anywhere else.
Catholics do have an 'education' problem.
