Again, partaking in some cultural observations is a far cry from religious indoctrination.
I have no problem with my kids singing "The First Noel" in school choir for the Christmas concert.
Now, if after the students finished singing during a practice session, and the teacher said, "Now, children. We just sang about the Baby Jesus. And you know, don't you, that if you and your Mommy and Daddy don't accept Jesus as your savior, you're all going to burn in Hell forever and ever..."
Well, THAT I might have a problem with. Although knowing my kids.. they'd probably just laugh at the teacher. If at first you don’t succeed – try, try again and then quit. There’s no sense in making a damned fool of yourself. – W.C. Fields |
