And what is TSA's response to a passenger who refuses to go along with this unpublished, unstated policy and pronounce their name? Seriously. I may find myself in this situation soon and would like to know.

Will it be like the ID thing--if you "willfully refuse" to pronounce your name, no flight, but if TSA (subjectively) decides you are unable to pronounce it, you get to fly?

Since when are Americans required to answer interrogations from government agents to go about their business? Policy or not, this one will be interesting when tested in court.
