At the beginning of my third year of medical school, a guy in my class named David, who was an Orthodox Jew, had a son. He sent an email out to our class, announcing the birth and informing us of the babies upcoming Bris (ritual circumcision).
For the record, David was one of the nicest people in the class. He was one of those guys who was always making study spreadsheets and then emailing them out to everyone to help them study. He was always trying to obtain Study aids to help everyone. He was only 24, but married to a really nice woman, and had been really excited about the baby.
Anyway, a few congratulations went out, then an email went out from an anonymous address, but that had to be from a member of our class because it quoted the original email that just went out to our class.
The email was a page long rant about circumcision. The email called David a "dumb Jew" and said that if he "believed in God so much, then he wouldn't take something away that God gave the child." The person then asked if he liked the taste of the foreskin in his mouth, and concluded by saying that David and his people were the cause of most turmoil in the world, and now he is added another Jew to the world.
I think we were all completely shocked that someone would send an email like that. Somebody in our class, who we knew and worked with and studied with. Somebody who was going to be a doctor soon.
And the disturbing thing is, we never found out who it was.
