When I was in college, I had a friend who invited my to an Alpha Epsilon Pi fraternity party. (A E Pi, as it was known, was the on-campus Jewish fraternity.) As far as I was concerned, frat parties and the AztecQueen do not mix. I'd heard too many stories of roofie rapes. However, when I said as much to my friend, she answered, "But you don't understand. They're Jewish!"
Really. The last time I checked, circumcision does not affect the hormones.
I've heard many people remark at the criminal sexual behaviors of various ethnicities, but I don't know where that came from. As Norma Rae put it, "I ain't never had any trouble with black men. Only trouble I ever had was with white men." Unfortunately, that extends to Jewish men. My first date with an Orthodox man, I had to tell him in no uncertain terms that he was going too far. So much for shomer negia. Suffice it to say, I never wanted to go out with him again. Even worse, that wasn't my first problem in that area. I used to babysit for my cantor's children. The cantor, who worked as a doctor, was separated from her husband and they split custody of their kids--and my services as babysitter. One night, her estranged husband made a pass at me in his car with his kids in the back. I was all of 19.
Yes, I am aware that there are a lot of Jewish men who know how to be gentlemen. Yes, these poor excuses for men are aberrations. But, I don't think we should assume that a man's Jewishness will automatically make him a safer, better person.
