After reading this article, I think that Mr Ong there is nothing right or wrong about Mr Ong.
In this 21st century, there's not problem being a homosexual. But the problem is he is a principal, a principal of Anglo-Chinese School, an independent and high reputational school that no one ever think that the principal is a gay.
Mr Tan, the victim of this incident did successfully manage to lodge a complaint to Mr Ong's behaviour. I think that after Mr Tan knew about his inappropriate behaviours, he should avoid travelling overseas with him alone to search for foreign students. Also, by reporting this incident, Mr Ong's pride was totally demoralised. Now that the whole world knows that he's a homosexual, I doubt that he can still face his family, relatives and friends.
Although I do not discriminate people who are homosexual, I think that Mr Ong should really resign his position and be sinful about his actions. Being a leader in the school, I think that he should set good examples for his teachers and students.
