For decades, Turkish school textbooks omitted any mention of Armenians as part of Ottoman history; more recently, textbooks have acknowledged that Armenians were subjected to mass deportation, but claimed that this action was justified and emphasized Armenian violence. Acknowledgment is punishable under Article 301 of the Penal Code, which prohibits insulting the Turkish nation and state institutions. Most Turkish citizens support the state's policies of denial, and the word "Armenian" became one of the worst insults in the Turkish language. However, many Kurds, who themselves have suffered political repression in Turkey, have recognized and condemned the genocide. In 2007, Turkish-Armenian journalist Hrant Dink, who had worked to promote reconciliation and acknowledgment of the genocide, was assassinated.
