We should be aware of going off to ‘Neverlands’ and totally rejecting our natural belonging within a certain community/culture in order to fit into the Ummah (which is not even a practical approach to begin with). Thus, it is quite possible to establish a grounded yet native Islamic presence within a given land, rather than mimic Arabs, Pakistanis, or other “Muslim ethnicities”.
And as a related note: Identities will be there. Even if we Muslims do not build our own identity, then this will be imposed on us from the outside and this is inevitable. Thus, we should proudly say that our mission is to eradicate the worship of all types of idols, otherwise a foreign identity will be stamped on us – an identity that will unfortunately include idol-worship of some sort.
