Hah.. Hope this doesn't hurt anyone's feelings but you shold see my LotR fan+teen-angst-anti-christian friends in a church. They modify every prayer and every religious song into some kind of Ilúvatar-religions -thing. And in a christian confirmation camp my friend intended to say to the priest that she can't pray the God because she believes in Eru. So that's sometimes funny but a bit ridiculous. My conclusion's that no one
really believes in Eru, but people might consider it as a nice joke or some fanatical fans might be gone too far...
