The phenomenon of nationalist digital vigilantism targeting Chinese intellectual women is rising in China. To illustrate how national identities and social exclusion are discursively constructed, as well as the potential vulnerabilities experienced by Chinese female intellectuals, four high-profile cases that took place between 2017 and 2021 are chosen. Critical discourse analysis is conducted on collected Sina Weibo comments, WeChat public account articles, and news articles published by state-run media. The research identifies three main discourses: the ungrateful traitor, the corrupt elite, and the ugly slut. These discursive interactions demonstrate the fluidity of both discursive and operational conditions in nationalist digital vigilantism, which amplifies the targets’ vulnerability. This research contributes to the study of misogynist populist nationalism by providing an empirical analysis in an under-studied social context—China, and to the study of Chinese populist nationalism by foregrounding an under-studied perspective—misogyny.
