Event Poster



Online social media platforms provide a battleground for propaganda and allow supporters of different political ideologies to increase the impact of their ideas and their fights with each other. This paper collects news and comment data from all of Hong Kong’s news media pages on Facebook since 2019, a period during which Hong Kong has witnessed frequent mass protests. Thanks to Hong Kong’s unique “one country, two systems” policy, we can for the first time study the ideological collision between two legitimate and coexisting systems, post-authoritarianism and pro-democracy, on an open online platform. The exogenous shocks of police-civil conflict and the unique writing habits of users from different backgrounds allow us to reveal the micromechanisms of how public response to the online content lead to the opinion polarization. We show that 1 additional anti-police comment was generated by every 3 pro-police comments and 1 additional comment on the demand for democracy in Hong Kong was generated by about 25 pro-police comments in Simplified Chinese. Our results demonstrate the counter-productivity of the effort to hire an “Internet Water Army” to influence public opinion on social media platforms.
