How do second-generation immigrant Muslims, born and raised in the UK, perceive themselves and present their identities in the post-9/11 social environment, where Islamophobia is pervasive? Muslim and British post-9/11 addresses this question through research in Muslim communities in East London and Coventry. Second-generation Muslims in Britain must struggle with negative discourses against Muslims and construct identities in response. In the process, using various self-presentation strategies based on religious knowledge, they demonstrate the model identity of 'British Muslim' - being civic by being religious - that multiculturalism can espouse. The author advocates that the identity and social integration of young Muslims in British society today can be better understood through the frame of reflexive modernization theory. From this perspective, he discusses diverse themes, including multiculturalism, women and agency, closed and open identities, information technology, the individualization of faith, and the semantics of the hijab to describe Islam as an 'everyday lived religion'.
