[Gwathagor]

This guy's an idiot.

First, if he can't spell the names right, why would I be inclined to believe the rest of his assertions of fact? He clearly is not very familiar with Middle-earth.

Second, the poem is descriptive, not prescriptive.

Third, he just makes stuff up - stuff that has no apparent basis in anything Tolkien wrote.

Fourth, he doesn't understand that a wizard means something rather different to Tolkien and the rest of the pre-D&D world than it does to him.

This is more funny than anything else and belongs in the crackpot theory drawer, along with Bombadil's secret life as the Witch-King of Angmar.
