"This is duplicitous fraud."

Belated reply. I do not think it is fraud unless you believe that a Jew can't - by definition - be a Christian. There are Jews who are atheists and agnostics, and if they can call themselves Jews why can't Jews who have accepted Jesus as the Messiah be called Jews? Jewish scholars such as Daniel Boyarin and Julie Galambush (a convert to Judaism) have written some excellent books on "the parting of the ways" between Judaism and Christianity, and the differences between the two belief systems in New Testament times were not nearly so vast as most people believe. The topic has been clouded by centuries of polemic on both sides.

I believe that a Jew can’t — by definition — be a Christian. This has been Jewish law, or Halacha, for a long, long time. Maimonides wrote about this nearly 1,000 years ago. What you say is “clouded by centuries of polemic from both sides” is really the same thing as what others might call “well-established principle” of nearly two millenia.
