THE letter 'Movie disgraceful' criticised the Gay and Lesbian Festival as immoral (Sunday Morning Post, February 5). So what kind of film does the writer, Paul Whittaker, think is moral and natural?

As a father of four, he should let his children know what's going on in our world and tell them what is right and what is wrong. ANDREW LEUNG CHUN-CHUNG Shek Tong Tsui
