This dissertation research analyzes the vernacular cosmopolitan praxis of Muslim women in transnational cyberspaces related to topical and collective action networks, in an effort to detangle cosmopolitanism from its Western biases and to move away from studies of online Muslim populations based on geographical locations or homogenous networks, linking individuals through their religious practices or consumption of religious knowledge. Through highlighting praxes rather than contexts, this dissertation disrupts the East/West binary and challenges stereotypes ascribed to Muslim women. One of the research questions related to the cosmopolitan praxis of Muslim women is the following: in what ways do Muslim women engage with "others" online and contribute to bridging dissimilar people? Findings suggest that the social media use of Muslim women contributes to their subtle resistance against communal norms and, although it can serve as an extension to their voices, some of their voices are more readily mediated than others. I employ a connective content analysis methodology to put various datasets associated with topics and collective actions related to Muslim women into conversation. The methodology not only highlights consistencies in the qualitative themes that were iteratively developed through the analyses of the datasets, but also more tangible connections related to social media users, topics, and content. Consequently, this thesis is as much concerned with recasting Western-oriented conceptualizations of cosmopolitanism as it is with how networks dynamics foster and constrain cosmopolitan praxis because digital networks have the extraordinary capacity to link dissimilar people beyond any other type of medium. One of the research questions related to the methodology is: how do network dynamics facilitate and constrain cosmopolitan praxis? The substantive chapters related to the datasets discuss various forms of cosmopolitan praxis that were identified in the analysis: social media use by Muslim women that expands the connective memory, which could contribute to dispelling stereotypes ascribed to them; activism that addresses universal concerns related to women's rights regardless of context; dialogically devising basic standards of social conduct and gender relations; and expressions of tolerance toward divergent views, including alternative interpretations of Islamic beliefs and practices.
