Gay students who set up an unauthorised book stall at City University yesterday were involved in a stand-off with security guards drafted in to evict them. Members of the Chinese University's Tongzhi Culture Society - the first student group registered to promote gay culture - were eventually forced to take the stall down. Five members ignored a City University ban and set up a temporary book stall at its Kowloon Tong campus on student registration day. They brought about 40 books on gay culture and displayed them near the Catholic Students' Society and the Inter-College Christian Fellowship counters. Security guards were called in and tried to remove their books but failed. The stand-off ended when the students took the books and left the campus voluntarily. Society members said they first approached the City University's students' union in June. 'They failed to give us a definite answer. First they said it was okay but then they said it wasn't,' group spokeswoman Franco Lai Yuen-ki said. Ms Lai suspected they were rejected because gay culture was still considered a taboo in the community. But the City University students' union denied the allegation, saying there was a misunderstanding. Union president Kenny Yuen Kin-chung said: 'There's no discrimination. The organisation was not rejected because of its nature. The venue is so small, we can't accept other outsiders.'
