Chapter 2 investigates the core concept of “Taiwan subjectivity” (台灣主體性) – the polity’s very “selfhood” – as Taiwan’s or the Republic of China’s (ROC’s) primary security referent. The chapter argues that Taiwan subjectivity is uniquely contested, as the PRC’s denial of its existence creates profound ontological insecurity for the Taiwanese people. The chapter then analyzes the deep internal divide between Taiwan’s Green (DPP) and Blue (KMT) communities over the identity of this state-self. Using Structural Topic Modeling (STM) to analyze commentary in the Liberty Times (Green) and United Daily News (Blue), the chapter maps two opposing securitization strategies. The Green discourse equates subjectivity with a de-Sinification imperative, forging an identity in direct opposition to China. Conversely, the Blue discourse promotes an ROC identity, rooted in a shared Chinese civilization, to create a far more cooperative Kantian culture of anarchy in the Strait. The analysis reveals that while both sides agree on the existence of a Taiwan self, their irreconcilable conflict over the self’s identity is a key factor in forging the cross-Strait Hobbesian culture.
