[the phantom]

I never said he did answer everything- I just said he liked to give answers.

There was no way he was going to produce a flawless world and story. There's too much of it. So he explored further the things that bothered him, the things that he thought were important, and left the rest alone. Who knows? If we lived as long as Elves, maybe Tolkien would have answered all those questions. But as our span of years is limited, and he was obviously aware of that, he couldn't and would certainly not set out to find a solution to every problem.

In addition, all of those examples you gave, besides Tom, are not at all like our Beorn dilemma. None of those things are out of place, or utterly baffling. Beorn is a problem because Tolkien's words conflict with themselves so violently. According to Tolkien's writing, Beorn could not be just a man. And yet, according to Tolkien, Beorn was a man.

Say what?

This has nothing in common with your examples. For instance, let's look at your Caradhras/Sauron situation. That is simply a mystery within the story where multiple sensible explanations could be given, and thus there is no certain right answer. Nothing about the event conflicts directly with Tolkien's world as defined by his words. He never said "Sauron can't make it snow" or "A spirit cannot take up residence in a mountain and have some sway over the local weather". Either would work. So naturally I have no problem with it.

But I do have a problem with Beorn, because he does not make sense within Middle Earth. By trying to find an explanation for him, I am essentially trying to stave off another Tom Bombadil, who is in an annoying league of his own. I can put up with one Tom Bombadil, but a book full of TBs....
