The national communications regulator has fined Taiwanese TV channel LS Time for broadcasting a lesbian kiss last February.
The $300,000 (Taiwanese dollars, $10,300, €7,900) fine was for a primetime showing of The Silent Thrush a 1992 film about a lesbian love triangle in a Chinese opera troupe.
In an open letter to the regulator National Communications Commission (NCC) Ta-wei Chi, assistant professor of Taiwanese Literature at the National Chengchi University in Taipei, questioned why they had a problem with homosexual kisses but not heterosexual ones.
Ta-wei suggested the NCC had been prejudiced to same-sex attracted people, Fridae reports.
The NCC was established in 2006 to regulate the industry. Taiwan has one of the least restricted media environments in Asia.
