So what happens when the (straight) associate rabbi at the Village's (gay) Congregation Beth Simchat Torah decides to get married in a state (New York) that doesn't allow same-sex unions? Rabbi Ayelet Cohen will put on a lacey Carmen Marc Valvo gown this Sunday, walk down the aisle, make a commitment to her husband-to-be, Rabbi Marc Margolius, and throw a traditional Jewish reception — "Hava Nagilah," raised chairs, food, cake, the whole megillah — for 200-odd guests at the Puck Building. But she won't actually, legally get married. "This is one of the major social injustices of our time," she said. "I cannot, in good conscience, participate in a system that actively excludes and discriminates against same-sex couples" — including her 4,000 congregants.
