"I believe it means what it says."
OK, I'll bite. It says "Christian Identity".
If it said "Christian Scientists", and you were a Baptist who worked at a national lab, would you worry that they were coming after you?
It takes a special kind of intelligence to parse "Christian Identity" as something other than the well-known neo-nazi outfit that goes by that name.
The term "Christian Identity" has two distinct meanings:
1. Anglo-Israelism (a.k.a. British-Israelism): A theological belief that the Anglo-Saxon, Celtic, Scandinavian, Germanic and associated cultures are the racial descendents of the tribes of Israel. Thus, by extension, Americans and Canadians, are composed of the descendents of the ancient Israelites of the Hebrew Scriptures (Old Testament).
2. Racist, Christian-based faith groups: A number of small, extremely conservative Fundamentalist Christian denominations which have accepted Anglo-Israelism, and grafted it to racist, sexist, anti-communist and homophobic beliefs. They view the Jewish people as descendants of Satan. Followers tend to be involved in political movements opposing gun control, equal rights to gays and lesbians, and militia movements.
The second meaning has become dominant in the U.S. and Canada. We will use it for the remainder of this essay.
