Dear Glenburne,
Actually, the only alternative to corrupting people is to keep them in ignorance, so I'm not completely against corruption. It just needs to be the right sort of corruption, and I don't think Beowulf will hurt your brother's innocence. I crinkle my nose at people who say they're against children being indoctrinated by fill in the blank-ists. It just means they want them indoctrinated with the doctrine which they prefer themselves.
Actually, Tolkien was a rather crabby old man, judging from his letters. He was nicer when he was younger. Conversely, I prefer C. S. Lewis's later works and imagine I would have liked the older Lewis better than the younger.
Sincerely,
Freckles
