I agree that there should be be no religious test (but alas, we all know there is one--see what would happen if an atheist were to run). 

I am not "splitting hairs"--the distinction between religion and culture (or race/ethnicity) is significant. Judaism, unlike Buddhism or Mormonism, is a cultural, racial and ethnic identity. It is also a religion. But the two do not always go together. If you were to ask a Buddhist or Mormon their race or ethnicity, they might say Thai, Tibetan, Lao, Caucasian, etc. They would not substitute their religion for their cultural identity. 

I have no idea why you think I am "self-appointed to find out who is a Jew"; in fact, I don't even know what you mean by that statement. Nor do I know what you mean by "Red Meat Blair" (and whether you're referring to the writer, Chad Blair, or to Patricia).
