I'm not exactly sure what you're asking. Used to think that I was geeky; then I went to a Star Trek convention

Much has been written regarding the attraction of Tolkien's works. Finding someone else who enjoys the same thing just adds that human connection, which we all need and may want.
And, having visited Graceland (the house of Elvis Presley), I've realized that we all have 'something;' ours is just LotR. It's probably due to some gene.
