You driver's license has your photo, making questions about race irrelevant.
I used to work in a hospital medical records dept. It was very useful to know a person's race, to be able to find out if the patient had been previously admitted. It's valuable to be able to access previous medical records. You'd be surprised to know how many peoplew have similar names; also, they don't always give the name in the same way: John Doe, J,B. Doe, J. Bernard Doe, Johnny Doe; then there are the spelling errors, J.Dough, John D'oh, it goes on and on.
Chill on the paranoia. You're already on most of the lists, there's nothing you can do about it except maybe change the way you give out your name to keep 'em confused.
Too late to worry about the political affiliation: I think the Supremes ruled that it was OK to release names of folks who sign petitions for or against things like gay marriage, even though the folks on the list were being threatened. Seemed to me that a petition should have the same privacy level as the secret ballot, but apparently I was wrong again.
