By Nicholas Kulish BERLIN – Six men whirled faster and faster in the center of the nightclub, arms slung over one another’s shoulders, performing a traditional circle dance popular in Turkey and the Middle East. Nothing unusual given the German capital’s large Muslim population. But most of the people filling the dance floor on Saturday at the club SO36 in the Kreuzberg neighborhood were gay, lesbian or bisexual, and of Turkish or Arab background. They were there for the monthly club night known as Gayhane, an all-too-rare opportunity to merge their immigrant cultures and their sexual identities.
