Okay, I'll bite. :P
Welcome to the Downs,
yeomanrycavalry. I hope to see more of you around, and I hope you enjoy being Dead.
Did Tolkien really intend to do all you have claimed he failed at? One can only fail at a thing if one was reaching for the goal. As Tolkien said, "my crest has long since fallen". So by the time he wrote LotR, he was trying to write a good ripping yarn and succeeded in doing a whole lot more than that. You can't fault a man for the culture to which he belonged.
