Irony

The New York Times prints an article "How do you prove you're a Jew?" on Jewish marriage, or something, by author named Gershom Gorenberg. Am I the only one who sees irony here? Of all the people who should be preoccupied enough about proving they're a Jew to write an article, Gershom should be last on the list. Aside from that, I have nothing else to say about the article because I don't care about its content one bit.
