Gandalf Vs. The Witch King

[obloquy]

You have completely ignored my argument about the letter, and have yet to provide any support for your opinion from the text. The conclusion that Gandalf and Sauron were equal is not a sudden jump in logic. I quote, once again:

To the overthrow of Morgoth he [Manwë] sent his herald Eönwë. To the defeat of Sauron would he not then send some lesser (but mighty) spirit of the angelic people, one coëval and equal, doubtless, with Sauron in their beginnings, but not more? Olórin was his name.

Even if you had provided a rock-solid defense of the letter's intended meaning, which you did not even attempt to do, it would still not have proved that the Witch-King had miraculously been pumped up to the level of a "peer" (to use Tolkien's word) of his master.
