Well, knock or no knock, DJ, it sounds to me like you are rationalizing a prejudice against folks with whom you simply don't agree. How would you know why another person didn't like those books as much as you did? Why reduce such people to a "type," examples of which you are glad to have identified? People enjoy what they enjoy. Why be angry about it.
I'm with you on that, though. I wish I liked the Middle Earth books as much as many do. As I said, I begrudge them none of that joy. And Tolkien is at least a good writer. I wish I could enjoy bad writers like Stephen King! But I genuinely don't, and I'm not going to lie about it for fear of getting on someone's stereotype list. Read what you love. I know I will.
