This paper aims to re-extend the theory and application of critical discourse analysis (CDA) by referring to Mikhail Bakhtin's dialogism. First, it read the concept of ”Being-as-event” and ”verbal interaction”, and argued that the character of contextualization and subjectivation of ordinary language should be regarded as the theoretical background for dialogism. Second, it analyzed the language process of resignification of the White Rose Movement, and explored the hidden possibility of ideological political struggle intrinsic into ordinary language. Based on the research findings, this paper concluded that Bakthin's dialogism not only contributes to propose an analytical framework of an interaction model to CDA which focuses on form of language and its moments, but also it could be appropriately used to analyze the bottom-up speech act and action in contemporary socio-cultural context.
