Studying identity politics is due to the social justice interest that women, sexual minorities, the disabled, ethnic or racial minorities, and non-regular and migrant workers, who have cultural identities that are different from governing or mainstream culture, should also be morally equal as human beings and should not be ignored or demeared as subordinate caste because they should be equally respected and cared for. That is why identity politics simply means paying more attention to the roles and rights of minorities, such as marginalized and alienated peoples, races and women, and recognizing their identity in our society. Therefore, in order to embody these goals, we must first understand how the conflicts of identity, which often occur in the era of Talideol, are formed through historical and cultural processes and expressed on a political level. Second, it is necessary to interpret from a radical democratic perspective how identity is distorted and transformed and reproduced in an era of multiculturalism. Third, it is necessary to reconstruct identity culturally and politically to seek a new face of identity, or the nonsuppression- free identity, from the perspective of global citizenship. The paper notes that a particular group expresses its cultural value by recreating its identity, but at the same time it can lead to tension, conflict and even violence by impulsing with the identity of other groups. In order for individuals with different values to coexist peacefully in one political community in a profound pluralistic society, on the one hand, we want to critically analyze the suppression system that enforces uniformity, and on the other, to reflect on the dual effects of identity politics, the liberation function and the violent function. Furthermore, we want to explore the possibility of freeing identity politics from oppression and violence by the concept of decentralized citizenship
