I seriously doubt that this is Dennis Miller.

It's not. It's Mr. W. Wayne Schields of Wichita Falls, Texas.

This particular offering did run in the Times Records News, the only newspaper in Wichita Falls, Texas. It appeared as a Letter to the Editor on 26 February 2003, with its author identified as W. Wayne Schields of Wichita Falls. How the piece came to be attributed to Dennis Miller remains a mystery.

Why is everything lately attributed to Dennis Miller?

This isn't his style, not by a long shot.

The all-caps kind of gives it away.
