Not sure what it has to do with the woman shooter, because she was not Jewish.
But Jewish people have common genetic thread therefore an ethnicity.
The Jewish people are one people with a common genetic thread that evolved in the second or third century BC.

I merely suggested the shooter COULD BE Jewish, which you proved was untrue. I live in NY and the ny post tends to be considered a rag, so I didnt read your link. However, if I converted to Judaism (which I know quite a few people who have done so) my ethnicity would not change.
