A feminist, Karlina also took part in revealing and defending the rights of victims of the Indonesian riots of May 1998, when hundreds of Chinese Indonesian women were raped in Jakarta. She went to the USA to persuade the US government to stop their export of weapons into Indonesia, resulting in death threats because of her activities. However, she was not deterred. She was also active in defending the rights of the Acehnese and East Timorese women who have been raped by members of the Indonesian army.
