the idea that all jews descend from abraham is a religious idea.

the jewish race is like anyother race. the reason why some people don't see them as any moe than "white" is because they are not black or asian. then again people wouldn't notice a slav walking down the street, or know the difference between a japanese and vietnamese person. it's a big thing in africa. small details that make one race different from the other that noone else would notice but still are racial differences. wars have been waged and genocide committed over that in africa. and the small differences between jew, slav, romany and aryan caused the holocaust.

i had an argument in history with a girl that wouldn't believe me that jewish was a race. it was hard to explain to her that when the gestapo man came round and asked you if you were jew instead of being able to see it most people would have denied it. (there is a true story of a racially jewish boy managing to get into the ss)

the kids in germany were taught how to spot a jew. the distinguishing features.

you can be jewish and christain. you can also be black and jewish.

there is great anti-semitic debate over whether jews are a race.
