You don’t accept that stereotypes are based at least somewhat on reality? Please.
I can speak for no other cultural or racial group. I can only say that having been a Jew for all of my 53 years, and having a very large extended family of Jews, in addition to my wife’s extended family, the stereotype of what the world thinks Jews are like has nothing to do with who we are.
How about the stereotype of people driven by hate and suspicion?
