Former chief executive Leung Chun-ying has more than 180,000 followers on Facebook. I am one of them. Love him or hate him, the subjects he touches on are almost always topical and controversial, and the stances he takes inevitably push some people’s hot buttons. His commentaries often become the next day’s newspaper headlines. Just for that, he is arguably the most important opinion leader of the city at the moment. It may be too far to call him Hong Kong’s Donald Trump, but what has been called Trumpism has had a profound effect on the political discourse of influential people in the city and on the mainland, and that includes Leung. In an obvious way, China’s diplomatic wolf warriors have taken after Trump, even as they attack the US president and his country. Though Trump may be peculiar to the domestic politics of the United States, Trumpism has certain key general characteristics: a disregard for etiquettes and norms, use of social media to be provocative rather than thoughtful, an unconcealed delight in insulting opponents, and a willingness to call out government officials, fairly or not. CY Leung amasses Facebook fans attacking Hong Kong officials, opposition alike People and groups attacked by Leung often end up becoming bigger targets to be criticised not only locally but at the national level. The Foreign Correspondents’ Club has been one of the most established and prestigious social institutions in Hong Kong. But in 2018, Leung launched an uncharacteristically fierce attack on the club for inviting Hong Kong separatist Andy Chan Ho-tin to give a talk, even calling for the cancellation of its long-standing lease. Since then, the club has become the bete noire of the blue-ribbon pro-government camp, culminating, unsurprisingly, with an attack from the local office of the foreign ministry last month for joining some local journalists’ groups in a protest against the police’s new accreditation rules. Until recently, “blue” groups have focused on attacking the opposition and anti-government groups for corrupting young people with their ideology. But recently, Leung has singled out the Education Bureau for not going after “yellow” teachers in local schools and refusing to disclose details of cases involving misconduct during last year’s unrest. Blue groups, political figures and online personalities have taken their cue and followed with their own attacks against the bureau and Kevin Yeung Yun-hung, the secretary for education. With his ability to mobilise conservative public opinion, Leung may be a more fearsome figure to people than when he was the chief executive.
