People are strange. Via NYPost: It was billed as a fiery exchange between a Jew and a Palestinian that prompted JetBlue to boot Dr. Lisa Rosenberg, a Queens gynecologist, from a flight on July 7. Turns out it was a fight between two New York Jews

The ugly incident unfolded in Florida on Flight 454 bound for JFK when Rosenberg spoke loudly of the Israeli-Palestinian crisis on her cellphone before takeoff.

A fellow passenger claiming to be an offended Palestinian approached her, and the conflict escalated. In headline-grabbing accusations, Rosenberg claimed she was bounced by anti-Semitic crew members. JetBlue insisted she falsely implied the rival passenger was carrying a bomb.

In a confessional phone call to Rosenberg's office last week, and in an interview with The Post, the fellow passenger revealed she is from Brooklyn and Jewish — even related to Menachem Begin, the late Israeli prime minister.

The woman, who did not give her name, explained she identified herself as Palestinian to stop Rosenberg's "hate-filled diatribe" against Palestinians.

"I told you at the time I was Palestinian because I wanted you to stop your rant. If I said I was Jewish, you wouldn't have stopped," the woman told Rosenberg, who recorded the conversation. "I shouldn't have said it, but I did."
