I don't object to fantasy or scifi. Grew up on it. But some is pretty juvenile in its treatment of human relationships, and that would include a lot of stories written by middle aged men who don't really like women. Whether they are gay or merely asexual, I don't know, but I can see why they would appeal to fifth grade boys.
There is certainly a place for such stories, but they aren't the end of the world.
Also this: "I can see why they would appeal to fifth grade boys" when you likely know that Tolkein is read by all ages and both sexes.
A couple of posters have pointed out that Tolkein was happily married with 4 kids, yet you constantly imply he had sexual problems, without seeming to know anything about him. Hard to find your comments credible.
The central story of the book is loyalty and friendship and human relationships. It may not come out and tell you "this is a human interaction, watch this!"
The trouble isn't that Tolkien is shallow, it is that you are. Good night.
