"People see themselves—and have reason to see themselves—in many different ways. For example, a Bangladeshi Muslim is not only a Muslim but also a Bengali and a Bangladeshi, typically quite proud of the Bengali language, literature, and music, not to mention the other identities he or she may have connected with class, gender, occupation, politics, aesthetic taste, and so on. Bangladesh's separation from Pakistan was not based on religion at all, since a Muslim identity was shared by the bulk of the population in the two wings of undivided Pakistan. The separatist issues related to language, literature, and politics.
Similarly, there is no empirical reason at all why champions of the Muslim past, or for that matter of the Arab heritage, have to concentrate specifically on religious beliefs only and not also on science and mathematics, to which Arab and Muslim societies have contributed so much, and which can also be part of a Muslim or an Arab identity.
