A Taiwanese gay couple said Tuesday they have received death threats after going public with a controversial appeal against the government for refusing to register their marriage. Chen Ching-hsueh and his partner Kao Chih-wei filed a complaint with the Taipei Administrative Court last year against a government agency that turned them away when they tried to register their marriage. While the general public had reacted positively, Chen said he got death threats and some offensive comments posted on his Facebook that prompted him to consider withdrawing his case. One threat sent via Facebook said Chen's parents would die. "I am not concerned about myself but I worry for my family," Chen, 40, told reporters, appearing with his 39-year-old partner. "I have to ask myself if it is worth it to go ahead with the case if my family is at risk of being harmed."
