When former radio host Wong Yuk-man won a seat in the Legislative Council last month, pundits predicted more fireworks in the new legislature. That is not far from the truth. Last week saw Donald Tsang Yam-kuen in the firing line of Mr Wong and two of his colleagues from the League of Social Democrats when the chief executive delivered his policy address and appeared at a post- address question-time session. Following two rounds of verbal abuse, first by 'Long Hair' Leung Kwok-hung, then by Mr Wong and Albert Chan Wai-yip, Mr Wong hurled a bunch of bananas onto the Legco president's dais before leaving the chamber during the Wednesday session. Mr Wong said later that Hong Kong's parliamentary culture was not lively enough. 'I hope for change ... People should get used to it [radical action], and [not] be so conservative,' he said. An expert in Taiwanese politics, Mr Wong may feel that his political theatrics were nothing compared with the scenes of flying fists, chairs and papers inside the island's Legislative Yuan in the 1980s. But Mr Wong's protest has drawn largely negative feedback from the public, mainly because it crossed the red line of acceptability regarding legislators' behaviour. Some commentators have likened the League members' outbursts to the Taiwanese-style political fights, which were greeted with awe and ridicule by Hong Kong people when they watched news footage two decades ago. Their negative perception of democratic politics on the island was embedded with images such as 'Taiwan's Rambo' Ju Gau-jeng wrestling and trading punches with other legislators. Admittedly, the League members' radical acts last week did not come out of the blue. Since being elected four years ago, Mr Leung has repeatedly attempted to challenge Legco rules and culture. But the media and public excitement about his unconventional political style being a breath of fresh air proved short-lived. When Mr Leung decided to seek re-election this year, analysts predicted he faced a battle for survival, as political radicalism and protest politics seemed to be losing their appeal. The election results, however, show that it does not appear to be the case. Both Mr Leung and Mr Wong, who was a first-timer in the poll, won with convincing margins. Together with its candidates in the other three geographical constituencies, the League grabbed about 10 per cent of the total vote. Many reasons have been given for the rise of radical politics: the widening income gap; alleged government-business collusion; and Mr Tsang's 'friend vs foe' governance approach. The League's approach has appealed to many voters, who are frustrated with the state of Hong Kong politics and would like to see change. The election results show that it was not just grass-roots voters but the middle class who voted for the League. Many of them are likely to be long-time supporters of pro-democracy candidates, and they probably hope that the League's members might be able to bring about change through a different approach. Such aspirations, however, should not be interpreted as an endorsement of a more aggressive political style. To them, radical politics is just a means to an end, not the end itself. If supporters discover that radical politics results in nothing more than a lot of hot air, and no new thinking on concrete issues, they will become disillusioned. And, at a time when the overall public image and support for the legislature is in decline, and tension lingers between the legislative and executive branches, excessive political stunts and radical politics risk deepening people's cynicism and despair about Hong Kong politics.
